Google’s whitepaper warns that quantum computers may break current cryptography by 2029. Computer scientist Guy Zyskind says post‑quantum cryptography—particularly lattice‑based schemes and encrypted mempools—is essential to secure blockchains. The Retroactive Decryption Trap: Why Post-Quantum Upgrades Can’t Save Your Past Privacy Reframing the 10-Year Migration Window The recently released Google whitepaper on the quantum threat has ignited intense debate over the technical justifications that led authors to aggressively pull forward the migration deadline to 2029. While a few critics have dismissed the findings as alarmist, a broad consensus of industry experts suggests that a warning of this magnitude from a primary driver of quantum research should serve as a definitive wake-up call for developers to begin immediate post-quantum preparations. Guy Zyskind, computer scientist and founder of Fhenix—a project integrating fully homomorphic encryption (FHE) into the Ethereum ecosystem—noted that the whitepaper effectively reframes the conversation. According to Zyskind, the traditional 10-year migration window, which until recently felt pessimistic, now appears “dangerously optimistic” in light of Google’s findings. Perhaps the most significant takeaway is the weight of the messenger itself; the fact that a tech titan of Google’s stature has attached its name to such a specific timeline should prod the blockchain community toward a fundamental architectural shift. Regarding why the findings in the whitepaper have gained traction, Zyskind said: “Previous papers in this space tended to be either too theoretical or too optimistic about qubit requirements. This one feels like it’s closing the gap in a way that should make people uncomfortable.” Meanwhile, the Google whitepaper’s core revelation has sent shockwaves through the blockchain community: Researchers have demonstrated that a “cryptographically relevant quantum computer” (CRQC) could achieve a 41% success rate in hijacking a transaction before it is even confirmed. Critics warn that this vulnerability could transform the mempool into a “shopping

Solana begins testing defenses against 'quantum-computing threat'… "Stronger security leads to slower performance" Summary - Solana (SOL) is reported to be conducting tests to apply post-quantum cryptography in cooperation with Project Eleven. - The tests confirmed the potential for stronger security, but also resulted in performance degradation, with data sizes increasing by 20–40 times and speeds slowing by about 90%. - CoinDesk reported that this clashes with Solana’s structure, which emphasizes fast processing, and assessed that it creates a dilemma between security and performance degradation. Forecast Trend Report by Period As Solana (SOL) begins testing security technologies to prepare for the era of quantum computers, early results reportedly confirmed a clear trade-off between tighter security and slower performance. According to CoinDesk, a cryptocurrency-focused outlet, on the 4th (Korea time) the Solana Foundation is conducting experiments to apply "post-quantum cryptography" in cooperation with the cryptography firm Project Eleven. Post-quantum cryptography is designed to prepare for the possibility that future quantum computers could break existing cryptographic systems. In fact, the industry has raised concerns that if quantum computers are realized, they could threaten the security of today’s blockchains. Test results suggest the chances of improving security are promising, but performance degradation emerged as security is strengthened. Specifically, post-quantum-resistant signature schemes were found to increase data size by 20–40 times compared with existing methods, while speeds fell by about 90%. CoinDesk assessed that "this conflicts with Solana’s architecture, which touts fast processing speeds as a key strength," adding that "the more security is strengthened, the more it creates a dilemma with performance degradation."

In brief - Algorand surged more than 40% over the past week after Google cited its "real-world deployment" of post-quantum protocols in a research paper. - Render gained almost 10% in 24 hours, driven by AI demand and adjacency to the trend. - Myriad users see an 82% chance that oil hits $120 next, as geopolitical uncertainty persists. Algorand has extended its rally over the past week, supported by a recent citation in a Google research paper singling out the blockchain as an early adopter of post-quantum protocols. Algorand jumped around 13% in the past 24 hours to $0.12, according to CoinGecko data, far outpacing the broader crypto market. It is up over 44% in the past week, a move experts attribute to growing interest in the quantum-resistant narrative. Google's whitepaper, "Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities," published on March 31, identified Algorand as an example of "real-world deployment of PQC on an otherwise quantum-vulnerable blockchain." The paper highlighted that Algorand had deployed post-quantum Falcon digital signatures for smart transactions and state proofs, executing its first PQC-secured transaction in 2025, and enabling native key rotation. “While this mechanism does not provide full quantum security at present, it facilitates future PQC migration,” the paper’s authors wrote. The rally reflects “renewed focus on quantum computing risks” following the publication of Google’s paper, Leo Fan, founder of Cysic and former lead on quantum resilience at Algorand, told Decrypt. “Algorand stands out because it has post-quantum signature schemes like Falcon live on the mainnet and was specifically referenced in the paper, giving it strong technical and narrative momentum,” he said. If the discussion around quantum security continues to gain traction, Fan added, it could “evolve into a durable market theme” grounded in credible long-term risk and institutional research support. Other analysts echoed Fan’s

Five Ways Quantum Technology Could Shape Everyday Life With billions invested and prototypes being tested outside the lab, the quantum era is starting to take shape. Image Credit IBM Share The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most powerful commercial quantum computer” mark just two of the latest developments in quantum technology’s increasingly rapid transition from experimental breakthroughs to practical applications. There is growing promise of quantum technology’s ability to solve problems that today’s systems struggle to overcome or cannot even begin to tackle, with implications for industry, national security, and everyday life. So, what exactly is quantum technology? At its core, it harnesses the counterintuitive laws of quantum mechanics, the branch of physics describing how matter and energy behave at the smallest scales. In this strange realm, particles can exist in several states simultaneously (superposition) and can remain connected across vast distances (entanglement). Once the stuff of abstract theory, these effects are now being engineered into innovative, cutting-edge systems: computers that process information in entirely new ways, sensors that measure the world with unprecedented precision, and communication networks that are virtually impossible to compromise. To understand how this emerging field could shape the future, here are five areas where quantum technology may soon have a tangible impact. 1. Discovery for Medicine and Materials Science A pharmaceutical scientist seeks to design a new medicine for a previously incurable disease. There are thousands of possible molecules, many ways they might interact inside the body, and uncertainty about which will work. In another lab, materials researchers explore thousands of different atomic combinations and ratios to develop better batteries, chemicals, and alloys to reduce transport emissions. Traditional supercomputers can narrow the options but eventually meet their limits. This is where quantum computing could make

Further Than Anyone Has Gone Before We’re on the cusp of the most extraordinary productivity boom in the history of the world. The entire internet will need to be upgraded to post-quantum encryption technologies. Managing Editor’s Note: Earlier this week, Jeff discussed in the issue Blockchains to Be Hacked by Quantum Computers the risk that rapid quantum computing developments pose to blockchain technology and, by extension, cryptocurrencies. But digital assets aren’t the only ones at risk… Quantum computing represents an unprecedented threat to the encryption systems that safeguard nearly all digital information and infrastructure today. As markets are closed today, we’re taking this opportunity to spotlight an issue where Jeff emphasizes the importance of equipping existing and future IT infrastructure with post-quantum encryption measures. There’s a quantum threat that’s building as quantum technology grows more advanced… The incredible developments of the last year or so in quantum computing – specifically the breakthroughs in quantum error correction – are signaling a once-in-a-generation shift in information technology (IT) infrastructure. The reality is daunting. The entire internet will need to be upgraded to post-quantum encryption technologies. Every piece of IT infrastructure will require post-quantum encryption software and hardware (semiconductors) to protect against quantum computers. This includes necessary upgrades for all communications systems and the current gold standard encryption technology. None of it will protect against the threat of quantum computing technology. Any stored file will also need to be re-encrypted using post-quantum encryption standards. Otherwise, files can be easily decrypted using quantum computers. Today, those knowledgeable in the industry about the latest advancements in quantum computing technology are already beginning this process of upgrading their IT systems. It’s still early, but those companies and government entities that are most sensitive to the threat of quantum computing systems are taking action now. The rest

Researchers have developed a tiny chip packed with dozens of miniature lasers that can transmit massive amounts of data simultaneously, reaching speeds over 360 gigabits per second in early tests. - Share: Fast, reliable wireless connections are essential in everyday life. Video calls, streaming, virtual reality, and connected devices all rely on networks that are already under heavy strain. Today, most wireless communication depends on radio-based technologies like Wi-Fi and cellular networks. While these systems have enabled global connectivity, they are running into growing challenges such as crowded radio frequencies, signal interference in busy indoor environments, and increasing energy demands as more devices come online. One emerging solution is optical wireless communication, which uses light instead of radio waves to transmit data. Light offers significantly more available bandwidth, avoids interference with existing wireless systems, and can be directed with high precision. These advantages make it especially appealing for indoor spaces like offices, homes, hospitals, data centers, and public venues where many users need fast connections at the same time. In a study published in Advanced Photonics Nexus, researchers developed a compact optical wireless transmitter that delivers both extremely high speeds and improved energy efficiency. The system is built around a tiny chip containing an array of semiconductor lasers, combined with an optical design that carefully controls how light is distributed. Together, these components create a scalable platform for high-capacity indoor wireless communication. Tiny

Thomas Huffstutler and colleagues at the Stony Brook University have identified the conditions under which quantum computers cannot outperform classical algorithms. Their work presents a key framework for definitively excluding the possibility of quantum speedups. The team utilise promise-aware complexity measures and function completions to determine when superpolynomial quantum speedups are unattainable for partial Boolean functions. This connection between the collapse of specific complexity measures and polynomially related deterministic and quantum query complexities offers sharp characterisations for structured function families. By formalising completion complexity, the study further identifies criteria for ruling out speedups in functions with predictable properties, advancing understanding of the limits of quantum computation. Defining computational limits using minimal function extension Completion complexity, a central technique in this analysis, operates much like filling in gaps in an incomplete puzzle to reveal the full picture. It is formally defined as the minimum complexity needed when extending a partial function, one defined for only some inputs, into a total function applicable to all inputs. This process of ‘completion’ isn’t arbitrary; it seeks the simplest total function consistent with the known values of the partial one, effectively minimising computational effort. Establishing criteria for when a quantum speedup is impossible is now possible through analysing how complexity measures change during this completion process, revealing fundamental limits to quantum computation. The approach was employed to determine when quantum computers can outperform classical algorithms, focusing on partial Boolean functions. Using a ‘gap parameter’ to characterise potential speedups, the analysis focused on symmetric functions and those defined on ‘slices’ of the input space. The minimum complexity of all possible total functions extending the partial one proved important in identifying limits to quantum computation and establishing criteria for when a quantum advantage is impossible. Polynomial relationships between deterministic and quantum query complexity for partial Boolean A

University of Chicago's "self-driving" lab automates experiments in quantum computing research Researchers at the University of Chicago have built a "self-driving" lab that uses robotics and artificial intelligence to accelerate work that would take humans weeks or months to complete. The autonomous lab at the University of Chicago Pritzker School of Molecular Engineering is the first "self-driving" lab of its kind in the Midwest. Instead of getting someone or something from point A to point B like a delivery robot or autonomous car, the "self-driving" lab automates tedious labor in experiments that would take high-level researchers weeks or even months to complete. "Basically combining artificial intelligence and robotic engineering," said Assistant Professor Shuolong Yang. The prototype is a high-speed shortcut to the building blocks of future quantum computers and electronics. The system learns as it goes. "I thought, why couldn't we use AI and robotics to automate this entire process?" said PhD student Bill Zheng. "The framework that we've developed here can help other material discovery as well." It's not replacing the people who built it, just allowing them to work on more. "They don't have to stay in the lab all day and all night doing this mechanical manual labor," Zheng said. There are countless applications, but there's a good example playing out across the Chicago area of why this work is so important – data centers, with many concerned about the amount of energy and resources required to run them. Experts estimate utility bills in the Chicago area could go up as much as $70 in the next three years because of data centers. Yang said quantum materials they're building with the help of the "self-driving" lab at the University of Chicago could reduce the energy consumption needed for data centers. "A superconductor mitigates that problem," Yang said.

Today’s operating landscape is full of pitfalls for businesses, particularly crypto-native ones. Companies that spent years building up bitcoin treasuries are now reportedly exiting the market, while on Wednesday (April 1) the Solana-based DeFi exchange Drift suffered an attack that drained $285 million in digital assets. And a new report from Google, titled “Safeguarding cryptocurrency by disclosing quantum vulnerabilities responsibly,” is only adding to the sector’s woes by highlighting the fact that quantum computing capable of breaking the cryptography underpinning bitcoin, ethereum and nearly the entire public chain ecosystem, is getting closer to reality. “We want to raise awareness on this issue and are providing the cryptocurrency community with recommendations to improve security and stability before this is possible, including transitioning blockchains to post-quantum cryptography (PQC), which is resistant to quantum attacks,” Google researchers wrote. The assertion cuts against the popular narrative that decentralized systems are inherently more resilient. Instead, Google’s analysis highlights a structural asymmetry: banks can quietly upgrade their cryptographic infrastructure, while public blockchains are bound by transparency, immutability and social consensus. Many systems rely on cryptographic primitives, especially elliptic curve signatures, that are theoretically vulnerable to sufficiently advanced quantum attacks. While those attacks remain impractical today, the exposure is already embedded in the chain.

Post-quantum cryptography emerges as top concern, followed by AI and automotive complexity. Key Takeaways: The most urgent security challenges in chips are no longer abstract quantum-secure algorithm choices or late-stage feature additions. They are architectural decisions that must be made early, under real constraints of area, power, performance, cost, with long product lifetimes. Several security issues directly impact silicon architecture, including the integration of post-quantum cryptography into real hardware, the widening gap between mathematically secure algorithms and physically secure implementations, and the growing exposure created by complex, multi-vendor supply chains. As systems scale into chiplets, heterogeneous compute, and software-defined platforms — particularly in automotive — architects are increasingly responsible for defining trust boundaries, key lifecycles, update mechanisms, and resilience against side-channel, fault-injection, and AI-accelerated attacks. Security must be treated as a first-order architectural constraint, designed into silicon from the outset, because once the masks are cut, there is no second chance. “Some of the most urgent security issues originate with the supply chain, because everyone is involved and there are established standards and certifications,” noted Sylvain Guilley, co-founder and CTO at Secure-IC, a Cadence company. “What makes it especially challenging is that it’s a system made up of multiple interconnected systems. If gaps exist, it’s crucial to focus on the interfaces between these systems when they’re combined. This is challenging, and it raises the question of responsibility. Whose business is it? Each party might be compliant individually, but unexpected issues can surface during integration. More transparency throughout the supply chain, along with improved auditability and traceability of how components are assembled, would be highly beneficial.” Work is already underway here, starting at the chiplet level. “We’re collaborating with standards organizations such as UCI Express and considering regulations like the Federal Acquisition Supply Chain Security Act (FASCSA) to establish traceability and

April 2, 2026 – Enschede, The Netherlands – QuiX Quantum, a leading provider of photonic quantum computing hardware, today announced it has demonstrated “below threshold” error mitigation for the first time on a photonic quantum computer, suppressing physical qubit errors to the level compatible with scalable, fault‑tolerant quantum computing. The achievement also marks the first time a European company has demonstrated a production-ready method of error reduction, demonstrating the scalability of the QuiX quantum computing platform based on photonics. The project was conducted on the QuiX BiaTM Cloud Quantum Computing Service in collaboration with NASA’s Quantum Artificial Intelligence Laboratory, the University of Twente, and Freie Universität Berlin. Quantum information is fragile, and without error correction, a computation of any user-relevant size will be impossible. For this reason, the ability to control errors in the quantum state is seen as a crucial milestone for any of the competing computing platforms. Increasingly, experts consider the ability to deal with such errors as the crucial differentiator between different technological approaches. For such a protocol to be meaningful, it must meet two conditions: it must remove more errors than it introduces, and it must not impede the operation of the rest of the computer. QuiX is the first party in photonics to demonstrate a protocol that meets both requirements simultaneously. The findings are described in a paper available at https://arxiv.org/abs/2601. “Below-threshold, physical error mitigation has never been implemented in a photonic quantum computer. This achievement marks a significant milestone and places QuiX Quantum at the forefront of progress toward fault-tolerant photonic quantum computing,” said Stefan Hengesbach, CEO of QuiX Quantum. “We believe the most resource-efficient strategy is to reduce errors early rather than correct them at great expense — and by demonstrating net positive error mitigation on real hardware, we’ve taken a foundational step

AWS Quantum Technologies Blog Decoding Realistic Quantum Error Syndrome with Quantum Elements Digital Twins Fault-tolerant quantum computing requires quantum error correction (QEC): Encoding one logical qubit into many physical qubits so that, below a threshold error rate, the logical error rate falls rapidly as the code grows. The practical engineering question is: How large must the code be and how good must the hardware be to reach a useful logical qubit? Credible answers require models that capture a device’s real error mechanisms, including coherent and correlated effects, yet run fast enough to support iterative design. These requirements motivate the design of hardware‑calibrated digital twins for QEC. As a step toward this goal, we report on results from a collaboration involving researchers from Quantum Elements Inc., the University of Southern California (USC), Harvard University and Amazon Web Services (AWS), to speed up hardware-faithful QEC simulations with classical compute resources. Building on a real-time quantum Monte Carlo (QMC) algorithm developed at USC [1], we used Amazon Elastic Compute Cloud (Amazon EC2) Hpc7a instances orchestrated by AWS ParallelCluster to run quantum master‑equation simulations of a distance‑7 rotated surface code with 97 physical qubits (49 data qubits + 48 measurement qubits) on par with the state-of-the-art surface-code memory demonstrations [2]. A full open-system simulation of a 97-qubit distance-7 surface code round without approximations would require tracking a density matrix with 4⁹⁷ entries, far beyond the capabilities of classical computers. Our approach runs this simulation in about an hour on a single compute node, while faithfully capturing coherent and correlated noise that simpler models miss. In this post, we present a foundational demonstration of scalable, hardware-faithful QEC simulations at experiment-relevant scale. In future posts, we will incorporate richer error models into the digital twin, use the resulting syndrome data to develop and evaluate more expressive
