Quantum Computing Moves Closer to Real-World Use as Researchers Push Past Major Technical Limits

 



The technology sector is preparing for another major transition, and this time the shift is not driven by artificial intelligence. Researchers have been investing in quantum computing for decades because it promises to handle certain scientific and industrial problems far faster than today’s machines. Tasks that currently require months or years of simulation – such as studying new medicines, designing materials for vehicles, or modelling financial risks could eventually be completed in hours or even minutes once the technology matures.


How quantum computers work differently

Conventional computers rely on bits, which store information strictly as zeros or ones. Quantum systems use qubits, which behave according to the rules of quantum physics and can represent several states at the same time. An easy way to picture this is to think of a coin. A classical bit resembles a coin resting on heads or tails. A qubit is like the coin while it is spinning, holding multiple possibilities simultaneously.

This ability allows quantum machines to examine many outcomes in parallel, making them powerful tools for problems that involve chemistry, physics, optimisation and advanced mathematics. They are not designed to replace everyday devices such as laptops or phones. Instead, they are meant to support specialised research in fields like healthcare, climate modelling, transportation, finance and cryptography.


Expanding industry activity

Companies and research groups are racing to strengthen quantum hardware. IBM recently presented two experimental processors named Loon and Nighthawk. Loon is meant to test the components needed for larger, error-tolerant systems, while Nighthawk is built to run more complex quantum operations, often called gates. These announcements indicate an effort to move toward machines that can keep operating even when errors occur, a requirement for reliable quantum computing.

Other major players are also pursuing their own designs. Google introduced a chip called Willow, which it says shows lower error rates as more qubits are added. Microsoft revealed a device it calls Majorana 1, built with materials intended to stabilise qubits by creating a more resilient quantum state. These approaches demonstrate that the field is exploring multiple scientific pathways at once.

Industrial collaborations are growing as well. Automotive and aerospace firms such as BMW Group and Airbus are working with Quantinuum to study how quantum tools could support fuel-cell research. Separately, Accenture Labs, Biogen and 1QBit are examining how the technology could accelerate drug discovery by comparing complex molecular structures that classical machines struggle to handle.


Challenges that still block progress

Despite the developments, quantum systems face serious engineering obstacles. Qubits are extremely sensitive to their environments. Small changes in temperature, vibrations or stray light can disrupt their state and introduce errors. IBM researchers note that even a slight shake of a table can damage a running system.

Because of this fragility, building a fault-tolerant machine – one that can detect and correct errors automatically remains one of the field’s hardest problems. Experts differ on how soon this will be achieved. An MIT researcher has estimated that dependable, large-scale quantum hardware may still require ten to twenty more years of work. A McKinsey survey found that 72 percent of executives, investors and academics expect the first fully fault-tolerant computers to be ready by about 2035. IBM has outlined a more ambitious target, aiming to reach fault tolerance before the end of this decade.


Security and policy implications

Quantum computing also presents risks. Once sufficiently advanced, these machines could undermine some current encryption systems, which is why governments and security organisations are developing quantum-resistant cryptography in advance.

The sector has also attracted policy attention. Reports indicated that some quantum companies were in early discussions with the US Department of Commerce about potential funding terms. Officials later clarified that the department is not currently negotiating equity-based arrangements with those firms.


What the future might look like

Quantum computing is unlikely to solve mainstream computing needs in the short term, but the steady pace of technical progress suggests that early specialised applications may emerge sooner. Researchers believe that once fully stable systems arrive, quantum machines could act as highly refined scientific tools capable of solving problems that are currently impossible for classical computers.

Google’s Quantum Breakthrough Rekindles Concerns About Bitcoin’s Long-Term Security

 




Google has announced a verified milestone in quantum computing that has once again drawn attention to the potential threat quantum technology could pose to Bitcoin and other digital systems in the future.

The company’s latest quantum processor, Willow, has demonstrated a confirmed computational speed-up over the world’s leading supercomputers. Published in the journal Nature, the findings mark the first verified example of a quantum processor outperforming classical machines in a real experiment.

This success brings researchers closer to the long-envisioned goal of building reliable quantum computers and signals progress toward machines that could one day challenge the cryptography protecting cryptocurrencies.


What Google Achieved

According to Google’s study, the 105-qubit Willow chip ran a physics algorithm faster than any known classical system could simulate. This achievement, often referred to as “quantum advantage,” shows that quantum processors are starting to perform calculations that are practically impossible for traditional computers.

The experiment used a method called Quantum Echoes, where researchers advanced a quantum system through several operations, intentionally disturbed one qubit, and then reversed the sequence to see if the information would reappear. The re-emergence of this information, known as a quantum echo, confirmed the system’s interference patterns and genuine quantum behavior.

In measurable terms, Willow completed the task in just over two hours, while Frontier, one of the world’s fastest publicly benchmarked supercomputers, would need about 3.2 years to perform the same operation. That represents a performance difference of nearly 13,000 times.

The results were independently verified and can be reproduced by other quantum systems, a major step forward from previous experiments that lacked reproducibility. Google CEO Sundar Pichai noted on X that this outcome is “a substantial step toward the first real-world application of quantum computing.”

Willow’s superconducting transmon qubits achieved an impressive level of stability. The chip recorded median two-qubit gate errors of 0.0015 and maintained coherence times above 100 microseconds, allowing scientists to execute 23 layers of quantum operations across 65 qubits. This pushed the system beyond what classical models can reproduce and proved that complex, multi-layered quantum circuits can now be managed with high accuracy.


From Sycamore to Willow

The Willow processor, unveiled in December 2024, is a successor to Google’s Sycamore chip from 2019, which first claimed quantum supremacy but lacked experimental consistency. Willow bridges that gap by introducing stronger error correction and better coherence, enabling experiments that can be repeated and verified within the same hardware.

While the processor is still in a research phase, its stability and reproducibility represent significant engineering progress. The experiment also confirmed that quantum interference can persist in systems too complex for classical simulation, which strengthens the case for practical quantum applications.


Toward Real-World Uses

Google now plans to move beyond proof-of-concept demonstrations toward practical quantum simulations, such as modeling atomic and molecular interactions. These tasks are vital for fields like drug discovery, battery design, and material science, where classical computers struggle to handle the enormous number of variables involved.

In collaboration with the University of California, Berkeley, Google recently demonstrated a small-scale quantum experiment to model molecular systems, marking an early step toward what the company calls a “quantum-scope” — a tool capable of observing natural phenomena that cannot be measured using classical instruments.


The Bitcoin Question

Although Willow’s success does not pose an immediate threat to Bitcoin, it has revived discussions about how close quantum computers are to breaking elliptic-curve cryptography (ECC), which underpins most digital financial systems. ECC is nearly impossible for classical computers to reverse-engineer, but it could theoretically be broken by a powerful quantum system running algorithms such as Shor’s algorithm.

Experts caution that this risk remains distant but credible. Christopher Peikert, a professor of computer science and engineering at the University of Michigan, told Decrypt that quantum computing has a small but significant chance, over five percent, of becoming a major long-term threat to cryptocurrencies.

He added that moving to post-quantum cryptography would address these vulnerabilities, but the trade-offs include larger keys and signatures, which would increase network traffic and block sizes.


Why It Matters

Simulating Willow’s circuits using tensor-network algorithms would take more than 10 million CPU-hours on Frontier. The contrast between two hours of quantum computation and several years of classical simulation offers clear evidence that practical quantum advantage is becoming real.

The Willow experiment transitions quantum research from theory to testable engineering. It shows that real hardware can perform verified calculations that classical computers cannot feasibly replicate.

For cybersecurity professionals and blockchain developers, this serves as a reminder that quantum resistance must now be part of long-term security planning. The countdown toward a quantum future has already begun, and with each verified advance, that future moves closer to reality.

Why Businesses Must Act Now to Prepare for a Quantum-Safe Future

 



As technology advances, quantum computing is no longer a distant concept — it is steadily becoming a real-world capability. While this next-generation innovation promises breakthroughs in fields like medicine and materials science, it also poses a serious threat to cybersecurity. The encryption systems that currently protect global digital infrastructure may not withstand the computing power quantum technology will one day unleash.

Data is now the most valuable strategic resource for any organization. Every financial transaction, business operation, and communication depends on encryption to stay secure. However, once quantum computers reach full capability, they could break the mathematical foundations of most existing encryption systems, exposing sensitive data on a global scale.


The urgency of post-quantum security

Post-Quantum Cryptography (PQC) refers to encryption methods designed to remain secure even against quantum computers. Transitioning to PQC will not be an overnight task. It demands re-engineering of applications, operating systems, and infrastructure that rely on traditional cryptography. Businesses must begin preparing now, because once the threat materializes, it will be too late to react effectively.

Experts warn that quantum computing will likely follow the same trajectory as artificial intelligence. Initially, the technology will be accessible only to a few institutions. Over time, as more companies and researchers enter the field, the technology will become cheaper and widely available including to cybercriminals. Preparing early is the only viable defense.


Governments are setting the pace

Several governments and standard-setting bodies have already started addressing the challenge. The United Kingdom’s National Cyber Security Centre (NCSC) has urged organizations to adopt quantum-resistant encryption by 2035. The European Union has launched its Quantum Europe Strategy to coordinate member states toward unified standards. Meanwhile, the U.S. National Institute of Standards and Technology (NIST) has finalized its first set of post-quantum encryption algorithms, which serve as a global reference point for organizations looking to begin their transition.

As these efforts gain momentum, businesses must stay informed about emerging regulations and standards. Compliance will require foresight, investment, and close monitoring of how different jurisdictions adapt their cybersecurity frameworks.

To handle the technical and organizational scale of this shift, companies can establish internal Centers of Excellence (CoEs) dedicated to post-quantum readiness. These teams bring together leaders from across departments: IT, compliance, legal, product development, and procurement to map vulnerabilities, identify dependencies, and coordinate upgrades.

The CoE model also supports employee training, helping close skill gaps in quantum-related technologies. By testing new encryption algorithms, auditing existing infrastructure, and maintaining company-wide communication, a CoE ensures that no critical process is overlooked.


Industry action has already begun

Leading technology providers have started adopting quantum-safe practices. For example, Red Hat’s Enterprise Linux 10 is among the first operating systems to integrate PQC support, while Kubernetes has begun enabling hybrid encryption methods that combine traditional and quantum-safe algorithms. These developments set a precedent for the rest of the industry, signaling that the shift to PQC is not a theoretical concern but an ongoing transformation.


The time to prepare is now

Transitioning to a quantum-safe infrastructure will take years, involving system audits, software redesigns, and new cryptographic standards. Organizations that begin planning today will be better equipped to protect their data, meet upcoming regulatory demands, and maintain customer trust in the digital economy.

Quantum computing will redefine the boundaries of cybersecurity. The only question is whether organizations will be ready when that day arrives.

Moving Toward a Quantum-Safe Future with Urgency and Vision


It is no secret that the technology of quantum computing is undergoing a massive transformation - one which promises to redefine the very foundations of digital security worldwide. Quantum computing, once thought to be nothing more than a theoretical construct, is now beginning to gain practical application in the world of computing. 

A quantum computer, unlike classical computers that process information as binary bits of zeros or ones, is a device that enables calculations to be performed at a scale and speed previously deemed impossible by quantum mechanics, leveraging the complex principles of quantum mechanics. 

In spite of their immense capabilities, this same power poses an unprecedented threat to the digital safeguards underpinning today's connected world, since conventional systems would have to solve problems that would otherwise require centuries to solve. 

 The science of cryptography at the heart of this looming challenge is the science of protecting sensitive data through encryption and ensuring its confidentiality and integrity. Although cryptography remains resilient to today's cyber threats, experts believe that a sufficiently advanced quantum computer could render these defences obsolete. 

Governments around the world have begun taking decisive measures in recognition of the importance of this threat. In 2024, the U.S. National Institute of Standards and Technology (NIST) released three standards on postquantum cryptography (PQC) for protecting against quantum-enabled threats in establishing a critical benchmark for global security compliance. 

Currently, additional algorithms are being evaluated to enhance post-quantum encryption capabilities even further. In response to this lead, the National Cyber Security Centre of the United Kingdom has urged high-risk systems to adopt PQC by 2030, with full adoption by 2035, based on the current timeline. 

As a result, European governments are developing complementary national strategies that are aligned closely with NIST's framework, while nations in the Asia-Pacific region are putting together quantum-safe roadmaps of their own. Despite this, experts warn that these transitions will not happen as fast as they should. In the near future, quantum computers capable of compromising existing encryption may emerge years before most organisations have implemented quantum-resistant systems.

Consequently, the race to secure the digital future has already begun. The rise of quantum computing is a significant technological development that has far-reaching consequences that extend far beyond the realm of technological advancement. 

Although it has undeniable transformative potential - enabling breakthroughs in sectors such as healthcare, finance, logistics, and materials science - it has at the same time introduced one of the most challenging cybersecurity challenges of the modern era, a threat that is not easily ignored. Researchers warn that as quantum research continues to progress, the cryptographic systems safeguarding global digital infrastructure may become susceptible to attack. 

A quantum computer that has sufficient computational power may render public key cryptography ineffective, rendering secure online transactions, confidential communications, and data protection virtually obsolete. 

By having the capability to decrypt information that was once considered impenetrable, these hackers could undermine the trust and security frameworks that have shaped the digital economy so far. The magnitude of this threat has caused business leaders and information technology leaders to take action more urgently. 

Due to the accelerated pace of quantum advancement, organisations have an urgent need to reevaluate, redesign, and future-proof their cybersecurity strategies before the technology reaches critical maturity in the future. 

It is not just a matter of adopting new standards when trying to move towards quantum-safe encryption; it is also a matter of reimagining the entire architecture of data security in the long run. In addition to the promise of quantum computing to propel humanity into a new era of computational capability, it is also necessary to develop resilience and foresight in parallel.

There will be disruptions that are brought about by the digital age, not only going to redefine innovation, but they will also test the readiness of institutions across the globe to secure the next frontier of the digital age. The use of cryptography is a vital aspect of digital trust in modern companies. It secures communication across global networks, protects financial transactions, safeguards intellectual property, and secures all communications across global networks. 

Nevertheless, moving from existing cryptographic frameworks into quantum-resistant systems is much more than just an upgrade in technology; it means that a fundamental change has been made to the design of the digital trust landscape itself. With the advent of quantum computing, adversaries have already begun using "harvest now, decrypt later" tactics, a strategy which collects encrypted data now with the expectation that once quantum computing reaches maturity, they will be able to decrypt it. 

It has been shown that sensitive data with long retention periods, such as medical records, financial archives, or classified government information, can be particularly vulnerable to retrospective exposure as soon as quantum capabilities become feasible on a commercial scale. Waiting for a definitive quantum event to occur before taking action may prove to be perilous in a shifting environment. 

Taking proactive measures is crucial to ensuring operational resilience, regulatory compliance, as well as the protection of critical data assets over the long term. An important part of this preparedness is a concept known as crypto agility—the ability to move seamlessly between cryptographic algorithms without interrupting business operations. 

Crypto agility has become increasingly important for organisations operating within complex and interconnected digital ecosystems rather than merely an option for technical convenience. Using the platform, enterprises are able to keep their systems and vendors connected, maintain robust security in the face of evolving threats, respond to algorithmic vulnerabilities quickly, comply with global standards and remain interoperable despite diverse systems and vendors.

There is no doubt that crypto agility forms the foundation of a quantum-secure future—and is an essential attribute that all organisations must possess for them to navigate the coming era of quantum disruption confidently and safely. As a result of the transition from quantum cryptography to post-quantum cryptography (PQC), it is no longer merely a theoretical exercise, but now an operational necessity. 

Today, almost every digital system relies heavily on cryptographic mechanisms to ensure the security of software, protect sensitive data, and authenticate transactions in order to ensure that security is maintained. When quantum computing capabilities become available to malicious actors, these foundational security measures could become ineffective, resulting in the vulnerability of critical data around the world to attack and hacking. 

Whether or not quantum computing will occur is not the question, but when. As with most emerging technologies, quantum computing will probably begin as a highly specialised, expensive, and limited capability available to only a few researchers and advanced enterprises at first. Over the course of time, as innovation accelerates and competition increases, accessibility will grow, and costs will fall, which will enable a broader adoption of the technology, including by threat actors. 

A parallel can be drawn to the evolution of artificial intelligence. The majority of advanced AI systems were confined mainly to academic or industrial research environments before generative AI models like ChatGPT became widely available in recent years. Within a few years, however, the democratisation of these capabilities led to increased innovation, but it also increased the likelihood of malicious actors gaining access to powerful new tools that could be used against them. 

The same trajectory is forecast for quantum computing, except with stakes that are exponentially higher than before. The ability to break existing encryption protocols will no longer be limited to nation-states or elite research groups as a result of the commoditization process, but will likely become the property of cybercriminals and rogue actors around the globe as soon as it becomes commoditised. 

In today's fast-paced digital era, adapting to a secure quantum framework is not simply a question of technological evolution, but of long-term survival-especially in the face of catastrophic cyber threats that are convergent at an astonishing rate. A transition to post-quantum cryptography (PQC), or post-quantum encryption, is expected to be seamless through regular software updates for users whose digital infrastructure includes common browsers, applications, and operating systems. 

As a result, there should be no disruption or awareness on the part of users as far as they are concerned. The gradual process of integrating PQC algorithms has already started, as emerging algorithms are being integrated alongside traditional public key cryptography in order to ensure compatibility during this transition period. 

As a precautionary measure, system owners are advised to follow the National Cyber Security Centre's (NCSC's) guidelines to keep their devices and software updated, ensuring readiness once the full implementation of the PQC standards has taken place. While enterprise system operators ought to engage proactively with technology vendors to determine what their PQC adoption timelines are and how they intend to integrate it into their systems, it is important that they engage proactively. 

In organisations with tailored IT or operational technology systems, risk and system owners will need to decide which PQC algorithms best align with the unique architecture and security requirements of these systems. PQC upgrades must be planned now, ideally as part of a broader lifecycle management and infrastructure refresh effort. This shift has been marked by global initiatives, including the publication of ML-KEM, ML-DSA, and SLH-DSA algorithms by NIST in 2024. 

It marks the beginning of a critical shift in the development of quantum-resistant cryptographic systems that will define the next generation of cybersecurity. In the recent surge of scanning activity, it is yet another reminder that cyber threats are continually evolving, and that maintaining vigilance, visibility, and speed in the fight against them is essential. 

Eventually, as reconnaissance efforts become more sophisticated and automated, organisations will not only have to depend on vendor patches but also be proactive in integrating threat intelligence, continuously monitoring, and managing attack surfaces as a result of the technological advancements. 

The key to improving network resilience today is to take a layered approach, which includes hardening endpoints, setting up strict access controls, deploying timely updates, and utilising behaviour analytics-based intelligent anomaly detection to monitor the network infrastructure for anomalies from time to time. 

Further, security teams should take an active role in safeguarding the entire network against attacks that can interfere with any of the exposed interfaces by creating zero-trust architectures that verify every connection that is made to the network. Besides conducting regular penetration tests, active participation in information-sharing communities can help further detect early warning signs before adversaries gain traction.

Attackers are playing the long game, as shown by the numerous attacks on Palo Alto Networks and Cisco infrastructure that they are scanning, waiting, and striking when they become complacent. Consistency is the key to a defender's edge, so they need to make sure they know what is happening and keep themselves updated.

AI and Quantum Computing: The Next Cybersecurity Frontier Demands Urgent Workforce Upskilling

 

Artificial intelligence (AI) has firmly taken center stage in today’s enterprise landscape. From the rapid integration of AI into company products, the rising demand for AI skills in job postings, and the increasing presence of AI in industry conferences, it’s clear that businesses are paying attention.

However, awareness alone isn’t enough. For AI to be implemented responsibly and securely, organizations must invest in robust training and skill development. This is becoming even more urgent with another technological disruptor on the horizon—quantum computing. Quantum advancements are expected to supercharge AI capabilities, but they will also amplify security risks.

As AI evolves, so do cyber threats. Deepfake scams and AI-powered phishing attacks are becoming more sophisticated. According to ISACA’s 2025 AI Pulse Poll, “two in three respondents expect deepfake cyberthreats to become more prevalent and sophisticated within the next year,” while 59% believe AI phishing is harder to detect. Generative AI adds another layer of complexity—McKinsey reports that only “27% of respondents whose organizations use gen AI say that employees review all content created by gen AI before it is used,” highlighting critical gaps in oversight.

Quantum computing raises its own red flags. ISACA’s Quantum Pulse Poll shows 56% of professionals are concerned about “harvest now, decrypt later” attacks. Meanwhile, 73% of U.S. respondents in a KPMG survey believe it’s “a matter of time” before cybercriminals exploit quantum computing to break modern encryption.

Despite these looming challenges, prioritization is alarmingly low. In ISACA’s AI Pulse Poll, just 42% of respondents said AI risks were a business priority, and in the quantum space, only 5% saw it becoming a top priority soon. This lack of urgency is risky, especially since no one knows exactly when “Q Day”—the moment quantum computers can break current encryption—will arrive.

Addressing AI and quantum risks begins with building a highly skilled workforce. Without the right expertise, AI deployments risk being ineffective or eroding trust through security and privacy failures. In the quantum domain, the stakes are even higher—quantum machines could render today’s public key cryptography obsolete, requiring a rapid transition to post-quantum cryptographic (PQC) standards.

While the shift sounds simple, the reality is complex. Digital infrastructures deeply depend on current encryption, meaning organizations must start identifying dependencies, coordinating with vendors, and planning migrations now. The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has already released PQC standards, and cybersecurity leaders need to ensure teams are trained to adopt them.

Fortunately, the resources to address these challenges are growing. AI-specific training programs, certifications, and skill pathways are available for individuals and teams, with specialized credentials for integrating AI into cybersecurity, privacy, and IT auditing. Similarly, quantum security education is becoming more accessible, enabling teams to prepare for emerging threats.

Building training programs that explore how AI and quantum intersect—and how to manage their combined risks—will be crucial. These capabilities could allow organizations to not only defend against evolving threats but also harness AI and quantum computing for advanced attack detection, real-time vulnerability assessments, and innovative solutions.

The cyber threat landscape is not static—it’s accelerating. As AI and quantum computing redefine both opportunities and risks, organizations must treat workforce upskilling as a strategic investment. Those that act now will be best positioned to innovate securely, protect stakeholder trust, and stay ahead in a rapidly evolving digital era.

AI Cryptography Encryption Identity Theft Policy Quantum computing Technology

Why Policy-Driven Cryptography Matters in the AI Era

 



In this modern-day digital world, companies are under constant pressure to keep their networks secure. Traditionally, encryption systems were deeply built into applications and devices, making them hard to change or update. When a flaw was found, either in the encryption method itself or because hackers became smarter, fixing it took time, effort, and risk. Most companies chose to live with the risk because they didn’t have an easy way to fix the problem or even fully understand where it existed.

Now, with data moving across various platforms, for instance cloud servers, edge devices, and personal gadgets — it’s no longer practical to depend on rigid security setups. Businesses need flexible systems that can quickly respond to new threats, government rules, and technological changes.

According to the IBM X‑Force 2025 Threat Intelligence Index, nearly one-third (30 %) of all intrusions in 2024 began with valid account credential abuse, making identity theft a top pathway for attackers.

This is where policy-driven cryptography comes in.


What Is Policy-Driven Crypto Agility?

It means building systems where encryption tools and rules can be easily updated or swapped out based on pre-defined policies, rather than making changes manually in every application or device. Think of it like setting rules in a central dashboard: when updates are needed, the changes apply across the network with a few clicks.

This method helps businesses react quickly to new security threats without affecting ongoing services. It also supports easier compliance with laws like GDPR, HIPAA, or PCI DSS, as rules can be built directly into the system and leave behind an audit trail for review.


Why Is This Important Today?

Artificial intelligence is making cyber threats more powerful. AI tools can now scan massive amounts of encrypted data, detect patterns, and even speed up the process of cracking codes. At the same time, quantum computing; a new kind of computing still in development, may soon be able to break the encryption methods we rely on today.

If organizations start preparing now by using policy-based encryption systems, they’ll be better positioned to add future-proof encryption methods like post-quantum cryptography without having to rebuild everything from scratch.


How Can Organizations Start?

To make this work, businesses need a strong key management system: one that handles the creation, rotation, and deactivation of encryption keys. On top of that, there must be a smart control layer that reads the rules (policies) and makes changes across the network automatically.

Policies should reflect real needs, such as what kind of data is being protected, where it’s going, and what device is using it. Teams across IT, security, and compliance must work together to keep these rules updated. Developers and staff should also be trained to understand how the system works.

As more companies shift toward cloud-based networks and edge computing, policy-driven cryptography offers a smarter, faster, and safer way to manage security. It reduces the chance of human error, keeps up with fast-moving threats, and ensures compliance with strict data regulations.

In a time when hackers use AI and quantum computing is fast approaching, flexible and policy-based encryption may be the key to keeping tomorrow’s networks safe.

Chinese Scientists Develop Quantum-Resistant Blockchain Storage Technology

 

A team of Chinese researchers has unveiled a new blockchain storage solution designed to withstand the growing threat posed by quantum computers. Blockchain, widely regarded as a breakthrough for secure, decentralized record-keeping in areas like finance and logistics, could face major vulnerabilities as quantum computing advances. 

Typically, blockchains use complex encryption based on mathematical problems such as large-number factorization. However, quantum computers can solve these problems at unprecedented speeds, potentially allowing attackers to forge signatures, insert fraudulent data, or disrupt the integrity of entire ledgers. 

“Even the most advanced methods struggle against quantum attacks,” said Wu Tong, associate professor at the University of Science and Technology Beijing. Wu collaborated with researchers from the Beijing Institute of Technology and Guilin University of Electronic Technology to address this challenge. 

Their solution is called EQAS, or Efficient Quantum-Resistant Authentication Storage. It was detailed in early June in the Journal of Software. Unlike traditional encryption that relies on vulnerable math-based signatures, EQAS uses SPHINCS – a post-quantum cryptographic signature tool introduced in 2015. SPHINCS uses hash functions instead of complex equations, enhancing both security and ease of key management across blockchain networks. 

EQAS also separates the processes of data storage and verification. The system uses a “dynamic tree” to generate proofs and a “supertree” structure to validate them. This design improves network scalability and performance while reducing the computational burden on servers. 

The research team tested EQAS’s performance and found that it significantly reduced the time needed for authentication and storage. In simulations, EQAS completed these tasks in approximately 40 seconds—far faster than Ethereum’s average confirmation time of 180 seconds. 

Although quantum attacks on blockchains are still uncommon, experts say it’s only a matter of time. “It’s like a wooden gate being vulnerable to fire. But if you replace the gate with stone, the fire becomes useless,” said Wang Chao, a quantum cryptography professor at Shanghai University, who was not involved in the research. “We need to prepare, but there is no need to panic.” 

As quantum computing continues to evolve, developments like EQAS represent an important step toward future-proofing blockchain systems against next-generation cyber threats.

Crypto Wallet Google Analyst Quantum computing RSA Encryption Technology

Google Researcher Claims Quantum Computing Could Break Bitcoin-like Encryption Easier Than Thought

 

Craig Gidney, a Google Quantum AI researcher, has published a new study that suggests cracking popular RSA encryption would take 20 times less quantum resources than previously believed.

Bitcoin, and other cryptocurrencies were not specifically mentioned in the study; instead, it focused on the encryption techniques that serve as the technical foundation for safeguarding cryptocurrency wallets and, occasionally, transactions.

RSA is a public-key encryption method that can encrypt and decrypt data. It uses two separate but connected keys: a public key for encryption and a private key for decryption. Bitcoin does not employ RSA and instead relies on elliptic curve cryptography. However, ECC can be overcome by Shor's algorithm, a quantum method designed to factor huge numbers or solve logarithm issues, which is at the heart of public key cryptography.

ECC is a method of locking and unlocking digital data that uses mathematical calculations known as curves (which compute only in one direction) rather than large integers. Consider it a smaller key that has the same strength as a larger one. While 256-bit ECC keys are much more secure than 2048-bit RSA keys, quantum risks scale nonlinearly, and research like Gidney's shrinks the period by which such assaults become feasible.

“I estimate that a 2048-bit RSA integer could be factored in under a week by a quantum computer with fewer than one million noisy qubits,” Gidney explained. This was a stark revision from his 2019 article, which projected such a feat would take 20 million qubits and eight hours. 

To be clear, no such machine exists yet. Condor, IBM's most powerful quantum processor to date, contains little over 1,100 qubits, while Google's Sycamore has 53. Quantum computing applies quantum mechanics concepts by replacing standard bits with quantum bits, or qubits. 

Unlike bits, which can only represent 0 or 1, qubits can represent both 0 and 1 at the same time due to quantum phenomena such as superposition and entanglement. This enables quantum computers to execute several calculations concurrently, potentially solving issues that are now unsolvable for classical computers. 

"This is a 20-fold decrease in the number of qubits from our previous estimate,” Gidney added. A 20x increase in quantum cost estimation efficiency for RSA might be an indication of algorithmic patterns that eventually extend to ECC. RSA is still commonly employed in certificate authorities, TLS, and email encryption—all of which are essential components of the infrastructure that crypto often relies on.

Quantum Computing Could Deliver Business Value by 2028 with 100 Logical Qubits

 

Quantum computing may soon move from theory to commercial reality, as experts predict that machines with 100 logical qubits could start delivering tangible business value by 2028—particularly in areas like material science. Speaking at the Commercialising Quantum Computing conference in London, industry leaders suggested that such systems could outperform even high-performance computing in solving complex problems. 

Mark Jackson, senior quantum evangelist at Quantinuum, highlighted that quantum computing shows great promise in generative AI applications, especially machine learning. Unlike traditional systems that aim for precise answers, quantum computers excel at identifying patterns in large datasets—making them highly effective for cybersecurity and fraud detection. “Quantum computers can detect patterns that would be missed by other conventional computing methods,” Jackson said.  

Financial services firms are also beginning to realize the potential of quantum computing. Phil Intallura, global head of quantum technologies at HSBC, said quantum technologies can help create more optimized financial models. “If you can show a solution using quantum technology that outperforms supercomputers, decision-makers are more likely to invest,” he noted. HSBC is already exploring quantum random number generation for use in simulations and risk modeling. 

In a recent collaborative study published in Nature, researchers from JPMorgan Chase, Quantinuum, Argonne and Oak Ridge national labs, and the University of Texas showcased Random Circuit Sampling (RCS) as a certified-randomness-expansion method, a task only achievable on a quantum computer. This work underscores how randomness from quantum systems can enhance classical financial simulations. Quantum cryptography also featured prominently at the conference. Regulatory pressure is mounting on banks to replace RSA-2048 encryption with quantum-safe standards by 2035, following recommendations from the U.S. National Institute of Standards and Technology. 

Santander’s Mark Carney emphasized the need for both software and hardware support to enable fast and secure post-quantum cryptography (PQC) in customer-facing applications.

RSA Encryption Breached by Quantum Computing Advancement

 


A large proportion of the modern digital world involves everyday transactions taking place on the internet, from simple purchases to the exchange of highly sensitive corporate data that is highly confidential. In this era of rapid technological advancement, quantum computing is both perceived as a transformative opportunity and a potential security threat. 

Quantum computing has been generating considerable attention in recent years, but as far as the 2048-bit RSA standard is concerned, it defies any threat these advances pose to the existing encryption standards that have been in use for decades. Several cybersecurity experts have expressed concern about quantum technologies potentially compromising military-grade encryption because of the widespread rumours.

However, these developments have not yet threatened robust encryption protocols like AES and TLS, nor do they threaten high-security encryption protocols like SLA or PKI. In addition to being a profound advancement over classical computing, quantum computing utilizes quantum mechanics principles to produce computations that are far superior to classical computation. 

Despite the inherent complexity of this technology, it has the potential to revolutionize fields such as pharmaceutical research, manufacturing, financial modelling, and cybersecurity by bringing enormous benefits. The quantum computer is a device that combines the unique properties of subatomic particles with the ability to perform high-speed calculations and is expected to revolutionize the way problems are solved across a wide range of industries by exploiting their unique properties. 

Although quantum-resistant encryption has been the focus of much attention lately, ongoing research is still essential if we are to ensure the long-term security of our data. As a major milestone in this field occurred in 2024, researchers reported that they were able to successfully compromise RSA encryption, a widely used cryptography system, with a quantum computer. 

To ensure the security of sensitive information transferred over digital networks, data encryption is an essential safeguard. It converts the plaintext into an unintelligible format that can only be decrypted with the help of a cryptographic key that is designated by the sender of the encrypted data. It is a mathematical value which is known to both the sender and the recipient but it is only known to them. This set of mathematical values ensures that only authorized parties can access the original information. 

To be able to function, cryptographic key pairs must be generated, containing both a public key and a private key. Plaintext is encrypted using the public key, which in turn encrypts it into ciphertext and is only decryptable with the corresponding private key. The primary principle of RSA encryption is that it is computationally challenging to factor large composite numbers, which are formed by multiplying two large prime numbers by two. 

Therefore, RSA encryption is considered highly secure. As an example, let us consider the composite number that is released when two 300-digit prime numbers are multiplied together, resulting in a number with a 600-digit component, and whose factorization would require a very long period if it were to be done by classical computing, which could extend longer than the estimated lifespan of the universe.

Despite the inherent complexity of the RSA encryption standard, this standard has proven to be extremely resilient when it comes to securing digital communications. Nevertheless, the advent of quantum computing presents a formidable challenge to this system. A quantum computer has the capability of factoring large numbers exponentially faster than classical computers through Shor's algorithm, which utilizes quantum superposition to perform multiple calculations at once, which facilitates the simultaneous execution of many calculations at the same time. 

Among the key components of this process is the implementation of the Quantum Fourier Transform (QFT), which extracts critical periodic values that are pertinent to refining the factorization process through the extraction of periodic values. Theoretically, a quantum computer capable of processing large integers could be able to break down the RSA encryption into smaller chunks of data within a matter of hours or perhaps minutes, effectively rendering the security of the encryption susceptible. 

As quantum computing advances, the security implications for cryptographic systems such as RSA are under increasing threat, necessitating that quantum-resistant encryption methodologies must be developed. There is a significant threat posed by quantum computers being able to decrypt such encryption mechanisms, and this could pose a substantial challenge to current cybersecurity frameworks, underscoring the importance of continuing to improve quantum-resistant cryptographic methods. 

The classical computing system uses binary bits for the representation of data, which are either zero or one digits. Quantum computers on the other hand use quantum bits, also called qubits, which are capable of occupying multiple states at the same time as a result of the superposition principle. As a result of this fundamental distinction, quantum computers can perform highly complex computations much faster than classical machines, which are capable of performing highly complex computations. 

As an example of the magnitude of this progress, Google reported a complex calculation that it successfully performed within a matter of seconds on its quantum processor, whereas conventional computing technology would have taken approximately 10,000 years to accomplish. Among the various domains in which quantum computing can be applied, a significant advantage can be seen when it comes to rapidly processing vast datasets, such as the artificial intelligence and machine learning space. 

As a result of this computational power, there are also cybersecurity concerns, as it may undermine existing encryption protocols by enabling the decryption of secure data at an unprecedented rate, which would undermine existing encryption protocols. As a result of quantum computing, it is now possible for long-established cryptographic systems to be compromised by quantum computers, raising serious concerns about the future security of the internet. However, there are several important caveats to the recent study conducted by Chinese researchers which should be taken into account. 

In the experiment, RSA encryption keys were used based on a 50-bit integer, which is considerably smaller and less complex than the encryption standards used today in security protocols that are far more sophisticated. RSA encryption is a method of encrypting data that relies on the mathematical difficulty of factoring large prime numbers or integers—complete numbers that cannot be divided into smaller fractions by factors. 

To increase the security of the encryption, the process is exponentially more complicated with larger integers, resulting in a greater degree of complexity. Although the study by Shanghai University proved that 50-bit integers can be decrypted successfully, as Ron Rivest, Adi Shamir, and Leonard Adleman have stressed to me, this achievement has no bearing on breaking the 2048-bit encryption commonly used in current RSA implementations. This achievement, however, is far from achieving any breakthrough in RSA. As a proof of concept, the experiment serves rather as a potential threat to global cybersecurity rather than as an immediate threat. 

It was demonstrated in the study that quantum computers are capable of decrypting relatively simple RSA encryption keys, however, they are unable to crack the more robust encryption protocols that are currently used to protect sensitive digital communications. The RSA algorithm, as highlighted by RSA Security, is the basis for all encryption frameworks across the World Wide Web, which means that almost all internet users have a vested interest in whether or not these cryptographic protections remain reliable for as long as possible. Even though this experiment does not signal an imminent crisis, it certainly emphasizes the importance of continuing to be vigilant as quantum computing technology advances in the future.

A Looming Threat to Crypto Keys: The Risk of a Quantum Hack

 


 The Quantum Computing Threat to Cryptocurrency Security

The immense computational power that quantum computing offers raises significant concerns, particularly around its potential to compromise private keys that secure digital interactions. Among the most pressing fears is its ability to break the private keys safeguarding cryptocurrency wallets.

While this threat is genuine, it is unlikely to materialize overnight. It is, however, crucial to examine the current state of quantum computing in terms of commercial capabilities and assess its potential to pose a real danger to cryptocurrency security.

Before delving into the risks, it’s essential to understand the basics of quantum computing. Unlike classical computers, which process information using bits (either 0 or 1), quantum computers rely on quantum bits, or qubits. Qubits leverage the principles of quantum mechanics to exist in multiple states simultaneously (0, 1, or both 0 and 1, thanks to the phenomenon of superposition).

Quantum Computing Risks: Shor’s Algorithm

One of the primary risks posed by quantum computing stems from Shor’s algorithm, which allows quantum computers to factor large integers exponentially faster than classical algorithms. The security of several cryptographic systems, including RSA, relies on the difficulty of factoring large composite numbers. For instance, RSA-2048, a widely used cryptographic key size, underpins the private keys used to sign and authorize cryptocurrency transactions.

Breaking RSA-2048 with today’s classical computers, even using massive clusters of processors, would take billions of years. To illustrate, a successful attempt to crack RSA-768 (a 768-bit number) in 2009 required years of effort and hundreds of clustered machines. The computational difficulty grows exponentially with key size, making RSA-2048 virtually unbreakable within any human timescale—at least for now.

Commercial quantum computing offerings, such as IBM Q System One, Google Sycamore, Rigetti Aspen-9, and AWS Braket, are available today for those with the resources to use them. However, the number of qubits these systems offer remains limited — typically only a few dozen. This is far from sufficient to break even moderately sized cryptographic keys within any realistic timeframe. Breaking RSA-2048 would require millions of years with current quantum systems.

Beyond insufficient qubit capacity, today’s quantum computers face challenges in qubit stability, error correction, and scalability. Additionally, their operation depends on extreme conditions. Qubits are highly sensitive to electromagnetic disturbances, necessitating cryogenic temperatures and advanced magnetic shielding for stability.

Future Projections and the Quantum Threat

Unlike classical computing, quantum computing lacks a clear equivalent of Moore’s Law to predict how quickly its power will grow. Google’s Hartmut Neven proposed a “Neven’s Law” suggesting double-exponential growth in quantum computing power, but this model has yet to consistently hold up in practice beyond research and development milestones.

Hypothetically, achieving double-exponential growth to reach the approximately 20 million physical qubits needed to crack RSA-2048 could take another four years. However, this projection assumes breakthroughs in addressing error correction, qubit stability, and scalability—all formidable challenges in their own right.

While quantum computing poses a theoretical threat to cryptocurrency and other cryptographic systems, significant technical hurdles must be overcome before it becomes a tangible risk. Current commercial offerings remain far from capable of cracking RSA-2048 or similar key sizes. However, as research progresses, it is crucial for industries reliant on cryptographic security to explore quantum-resistant algorithms to stay ahead of potential threats.

Quantum computing, unlike AI, is shrouded in scientific complexity and public obscurity. While AI benefits from widespread cultural familiarity, quantum mechanics remains an enigmatic topic, rarely explored in blockbuster movies or bestselling novels. Despite its low profile, quantum computing harbors transformative—and potentially hazardous—capabilities.

Quantum computers excel at solving problems beyond the scope of today's classical computers. For example, in 2019, Google’s quantum computer completed a computation in just over three minutes—a task that would take a classical supercomputer approximately 10,000 years. This unprecedented speed holds the promise to revolutionize fields such as healthcare, logistics, and scientific research. However, it also poses profound risks, particularly in cybersecurity.

The most immediate threat of quantum computing lies in its ability to undermine existing encryption systems. Public-key cryptography, which safeguards online transactions and personal data, relies on mathematical problems that are nearly impossible for classical computers to solve. Quantum computers, however, could crack these codes in moments, potentially exposing sensitive information worldwide.

Many experts warn of a “cryptographic apocalypse” if organizations fail to adopt quantum-resistant encryption. Governments and businesses are beginning to recognize the urgency. The World Economic Forum has called for proactive measures, emphasizing the need to prepare for the quantum era before it is too late. Despite these warnings, the public conversation remains focused on AI, leaving the risks of quantum computing underappreciated.

The race to counter the quantum threat has begun. Leading tech companies like Google and Apple are developing post-quantum encryption protocols to secure their systems. Governments are crafting strategies for transitioning to quantum-safe encryption, but timelines vary. Experts predict that quantum computers capable of breaking current encryption may emerge within 5 to 30 years. Regardless of the timeline, the shift to quantum-resistant systems will be both complex and costly.

While AI captivates the world with its promise and peril, quantum computing remains an under-discussed yet formidable security challenge. Its technical intricacy and lack of cultural presence have kept it in the shadows, but its potential to disrupt digital security demands immediate attention. As society marvels at AI-driven futures, it must not overlook the silent revolution of quantum computing—an unseen threat that could redefine our technological landscape if unaddressed.

Cybersecurity in APAC: AI and Quantum Computing Bring New Challenges in 2025

 



Asia-Pacific (APAC) enters 2025 with serious cybersecurity concerns as new technologies such as artificial intelligence (AI) and quantum computing are now posing more complex threats. Businesses and governments in the region are under increased pressure to build stronger defenses against these rapidly evolving risks.

How AI is Changing Cyberattacks

AI is now a primary weapon for cybercriminals, who can now develop more complex attacks. One such alarming example is the emergence of deepfake technology. Deepfakes are realistic but fake audio or video clips that can mislead people or organizations. Recently, deepfakes were used in political disinformation campaigns during elections in countries such as India and Indonesia. In Hong Kong, cybercriminals used deepfake technology to impersonate individuals and steal $25 million from a company. Audio-based deepfakes, and in particular, voice-cloning scams, will likely be used much more by hackers. It means that companies and individuals can be scammed with fake voice recordings, which would increase when this technology gets cheaper and becomes widely available. As described by Simon Green, the cybersecurity leader, this situation represents a "perfect storm" of AI-driven threats in APAC.

The Quantum Computing Threat

Even in its infancy, quantum computing threatens future data security. One of the most pressing is a strategy called "harvest now, decrypt later." Attackers will harvest encrypted data now, planning to decrypt it later when quantum technology advances enough to break current encryption methods.

The APAC region is moving at the edge of quantum technology development. Places like India, Singapore, etc., and international giants like IBM and Microsoft continue to invest so much in such technology. Their advancement is reassuring but also alarms people about having sensitive information safer. Experts speak about the issue of quantum resistant encryption to fend off future threat risks.

With more and more companies embracing AI-powered tools such as Microsoft Copilot, the emphasis on data security is becoming crucial. Companies have now shifted to better management of their data along with compliance in new regulations in order to successfully integrate AI within their operations. According to a data expert Max McNamara, robust security measures are imperative to unlock full potential of AI without compromising the privacy or safety.

To better address the intricate nature of contemporary cyberattacks, many cybersecurity experts suggest unified security platforms. Integrated systems combine and utilize various instruments and approaches used to detect threats and prevent further attacks while curtailing costs as well as minimizing inefficiencies.

The APAC region is now at a critical point for cybersecurity as threats are administered more minutely. Businesses and governments can be better prepared for the challenges of 2025 by embracing advanced defenses and having the foresight of technological developments.

Bitcoin Security Concerns Amid Quantum Computing Advancements

 

Chamath Palihapitiya, CEO of Social Capital, has raised alarms over Bitcoin’s future security, cautioning that its SHA-256 encryption may become vulnerable within the next two to five years. Speaking on the All-In Podcast, he highlighted rapid advancements in quantum computing, particularly Google’s unveiling of the Willow quantum chip featuring 105 qubits. Palihapitiya estimates that 8,000 such chips could potentially breach SHA-256 encryption, underscoring the pressing need for blockchain networks to adapt.

Quantum Computing's Impact on Cryptography

While acknowledging the infancy of quantum computing, Palihapitiya pointed to Google’s Willow chip as a pivotal development that could accelerate breakthroughs in cryptography. Despite scalability challenges, he remains optimistic that the cryptocurrency sector will evolve to develop quantum-resistant encryption methods.

Not all experts share his concerns, however. Ki Young Ju, founder of CryptoQuant, has expressed confidence that Bitcoin’s encryption is unlikely to face quantum threats within this decade.

Satoshi Nakamoto’s Early Solutions

Bitcoin’s pseudonymous creator, Satoshi Nakamoto, had anticipated such scenarios. In 2010, Satoshi proposed that the Bitcoin community could agree on the last valid blockchain snapshot and transition to a new cryptographic framework if SHA-256 were compromised. However, these early solutions are not without controversy.

Emin Gün Sirer, founder of Avalanche, has warned that some of Satoshi’s early-mined coins used an outdated Pay-To-Public-Key (P2PK) format, which exposes public keys and increases the risk of exploitation. Sirer suggested the Bitcoin community should consider freezing these coins or setting a sunset date for outdated transactions to mitigate risks.

Recent advancements in quantum computing, including Google’s Willow chip, briefly unsettled the cryptocurrency market. A sudden wave of liquidations resulted in $1.6 billion being wiped out within 24 hours. However, Bitcoin demonstrated resilience, reclaiming the $100,000 resistance level and achieving a 4.6% weekly gain.

Proactive Measures for Long-Term Security

Experts widely agree that proactive steps, such as transitioning to quantum-resistant cryptographic frameworks, will be essential for ensuring Bitcoin’s long-term security. As the quantum era approaches, collaboration and innovation within the cryptocurrency community will be pivotal in maintaining its robustness against emerging threats.
