Abstract Following any quantum information processing protocol, it is essential to reset a mixed state of a many-body interacting spin-network to the computational-zero pure state. This task is challenging, both theoretically and experimentally, because of the quantum correlations. There is currently no effective cooling strategy for both high and low temperatures in such networks. Here we put forth a universal cooling strategy for multi-spin interacting networks. The strategy is based on the collective coupling of the system to an ancilla spin that intermittently dumps part of its entropy into an ultracold bath. Yet this strategy should overcome the symmetry-imposed correlations that impede the cooling. To avoid the prohibitive complexity of computing the dynamics, we resort to graph analysis of the network. We show that a unique choice of alternating, non-commuting system-ancilla interaction Hamiltonians exists that breaks the symmetry constraints and allows the network to approach the desired pure state. We illustrate this universal purification strategy in diverse experimental settings.

Wellcome Leap has announced that a multidisciplinary team led by the Finnish quantum software company Algorithmiq is the winner of the $2 million Quantum for Bio (Q4Bio) Supported Challenge prize. The 30-month, $50 million initiative was designed to accelerate the development of quantum algorithms specifically for human health. While today’s quantum computers are not yet capable of outperforming classical machines in biology (a milestone known as “quantum advantage”), the prize recognizes the first experimental realization of an end-to-end quantum-classical workflow for a complex therapeutic, providing a scalable roadmap for future health breakthroughs. The winning project, conducted in collaboration with IBM and the Cleveland Clinic, focused on photodynamic therapy (PDT)—a cancer treatment that utilizes light-activated drugs (photosensitizers) to destroy tumors with minimal toxicity to surrounding tissue. Using an IBM Quantum System One located at the Cleveland Clinic, the team successfully simulated the excited-state properties of a photosensitizer drug. This required replicating the complex interaction between photons and electrons, a task specifically suited for quantum computation. The demonstration utilized 100 qubits and achieved circuit depths between 1,000 and 10,000 gates, meeting the rigorous technical criteria established by Wellcome Leap. Beyond the winning entry, the Q4Bio program whittled dozens of applicants down to six finalists, each of whom made significant contributions to the life sciences computational stack. The University of Oxford and the Sanger Institute achieved a technical first by encoding a viral genome (Hepatitis-D) onto quantum hardware, while a team led by Infleqtion and the University of Chicago utilized hybrid quantum-classical optimization to discover novel multimodal cancer biomarkers. Other finalists, including teams from Stanford and the University of Nottingham, explored biochemical reactions like ATP hydrolysis and the design of covalent inhibitors for untreatable genetic disorders. One of the program’s most significant outcomes was the shift from theoretical exploration to “utility-scale” hardware validation.

Voyager Space and IBM have successfully demonstrated a post-quantum secured communication link between Earth and the International Space Station (ISS). This orbital milestone utilized Voyager’s Space Edge™ Micro Datacenter, which was launched to the ISS in September 2025, and IBM Quantum Safe Remediator software. The project proves that satellite data—critical for national defense, weather forecasting, and commercial telecommunications—can be protected against future quantum computing attacks using current infrastructure. The demonstration addressed a primary challenge in space security: “crypto-agility.” Most orbital hardware has embedded encryption that is difficult to upgrade without physical replacement. To bypass this, IBM’s Quantum Safe Remediator acted as an intelligent proxy around legacy applications, translating classical encryption internally while communicating with the outside world via NIST-standardized post-quantum cryptography (PQC) algorithms. This allows existing space infrastructure to adopt new security standards without requiring extensive application code changes or hardware overhauls. As the industry approaches the “danger zone” at the end of this decade—when quantum computers may become capable of breaking traditional encryption—the risk of “harvest now, decrypt later” attacks has become a central concern for LEO (Low Earth Orbit) and lunar missions. Dennis Gatens, President of LEOcloud at Voyager, emphasized that as orbital computing becomes critical infrastructure, maintaining data integrity on-orbit is as vital as terrestrial security. This collaboration aligns with the U.S. government mandate for all agencies to adopt a PQC posture by 2035, establishing a blueprint for secure deep-space and lunar communications.

Every investor is always looking for the next multibagger. This pulls from a baseball analogy, and one "bag" indicates a stock doubling. So, a multibagger investment doubles multiple times. Unlike baseball, where the maximum is four bags from a home run, stocks technically have unlimited upside, and several 100-baggers exist. One field where investors are looking for the next multibagger is in quantum computing. While quantum technology isn't yet widely used, it's rapidly progressing to the point where it could see mainstream usage by 2030. That's not that far away, and investors should position themselves accordingly if quantum computing lives up to the hype. One popular investment choice in this industry is IonQ (IONQ +3.31%). IonQ is a leader in the quantum computing realm and has captured the attention of the investment community. But is it the next multibagger? Let's take a look. IonQ has the most accurate platform available The question is not if one can do quantum computing. Quantum computing technology is widely available today and can be used right now. The biggest issue is whether one can trust the results that quantum computers produce. These systems are prone to errors, and if users cannot trust that the system is outputting, then their advantages are practically useless. IonQ is a popular quantum computing stock pick right now because it holds the world record for the most accurate quantum computer. Back in October 2025, it established a new record of 99.99% two-qubit gate fidelity, a measure of how accurate a calculation is after passing through two processing gates. Most other companies have struggled to achieve 99.9% fidelity, which is still a long way off from where IonQ currently is.

- New Bitcoin upgrade proposal splits opinions. - Developers say freezing Bitcoin in vulnerable wallets is necessary to defend against a potential quantum attack. - A future quantum computer could threaten the $1.5 trillion blockchain. Satoshi Nakamoto is one of the richest people in the world, but a new proposal risks locking away the Bitcoin founder’s trove forever. A group of six Bitcoin developers and quantum computer experts have proposed permanently deactivating vulnerable wallets in a bid to protect the network from future quantum attacks. The proposal, published on Tuesday, would upgrade the blockchain to stop users from sending Bitcoin to vulnerable wallets, and eventually reject any transaction from those wallets at a predetermined point in the future. Bitcoin left in vulnerable wallets at that time would become permanently locked away, although the developers say measures could be put in place to allow owners to recover their coins. Many Bitcoin proponents have already slammed the proposal. They say it is authoritarian, punishes long-term holders, and goes against Bitcoin’s core values as a neutral and immutable asset. “I know folks don't like it. I don't like it myself. I wrote it because I like the alternative even less,” said Jameson Lopp, a prominent Bitcoin developer and one of the proposal’s authors. “I hope it never needs to be considered for adoption.” The move comes amid fears that the development of superfast computers that make use of quantum phenomena is accelerating. Such a computer could theoretically break the encryption that underpins not just Bitcoin but much of the encryption that digital infrastructure is built around, too. A June report from consulting firm McKinsey & Company predicts that based on the current rate of development, a cryptographically-relevant quantum computer could be developed as early as next year.

Xanadu Quantum Technologies Ltd. has been on a wild stock market ride since going public three weeks ago. The Toronto company, which went public by merging with a Nasdaq-listed special-purpose acquisition company, saw its share price slide after its strong trading debut on March 27. It closed that day at US$11.50 but ended last Thursday at US$7.65. Since then, the stock has been on an exponential tear, appreciating in value by increasingly higher double-digit percentages each day. The stock closed up 17.1 per cent last Friday, 28.2 per cent on Monday, 29 per cent on Tuesday and 70 per cent on Wednesday, ending at US$25.18. Xanadu, which is also listed on the Toronto Stock Exchange, appreciated so rapidly late Wednesday morning that it triggered a temporary trading halt on the Canadian exchange for a few minutes. That made Xanadu Canada’s fifth-most valuable publicly traded technology company, with a market capitalization of US$7.5-billion. Founder and chief executive officer Christian Weedbrook, who has 46.4 million multiple voting shares, is now a billionaire, though he has said he doesn’t pay much attention to the stock price. Much of this week’s gains happened after chip behemoth Nvidia Corp. said Tuesday that its new open-source family of artificial intelligence models, called Ising, will enable researchers and businesses to speed up the performance and accuracy of the decoding process needed to correct errors that are part of the process of quantum computing operations. Reducing errors is a key challenge all quantum computer developers must solve before their machines can operate at full scale.

Wang Liao and colleagues at University of Tokyo have created KOVAL-Q, a new electronic design automation (EDA) kernel that verifies and optimises surface-code logical operations by translating them into a satisfiability problem. The approach enables greater flexibility in surface-code encodings and expands the possibilities for advanced layouts, such as fast blocks. Demonstrations show KOVAL-Q can identify the quickest way to perform key logical operations, reducing the execution time of established quantum computing applications by approximately 10% under a simplified model. Its modular design enables integration with larger heuristic frameworks. KOVAL-Q optimises fault-tolerant quantum computation via satisfiability-driven surface-code logic A new electronic design automation kernel, KOVAL-Q, has decreased execution times for widely studied fault-tolerant quantum computing applications by approximately 10%. This improvement arises from KOVAL-Q’s ability to discover and optimise logical operations on two-qubit surface-code patches, a capability previously unavailable with methods like LaSsynth. The framework achieves this by formulating these operations as a satisfiability problem. This is a standard approach in computer science where the goal is to determine if there exists an assignment of variables that satisfies a given Boolean formula. This broadening of the search space enables more flexible surface-code encodings. Surface codes are a leading candidate for error correction in quantum computers, and optimising their implementation is crucial for building practical devices. Its modular design also allows seamless integration into larger heuristic frameworks, providing a key tool for optimising and validating core fault-tolerant quantum computing subroutines. The significance of this lies in the potential to reduce the overhead associated with quantum error correction, a major hurdle in scaling up quantum computers. The framework determines the minimum execution time of logical CNOT gates and patch rotations, requiring only ‘d’ and ‘2d’ stabiliser measurement cycles respectively, where ‘d’ represents the distance parameter of the surface code, a key metric

Space Edge™ Enables Crypto-agility Many experts in the field of post-quantum cryptography (PQC) pinpoint the end of this decade as the “danger zone” for traditional encryption — the timeframe in which it is likely that a quantum computer will be available with the capability to break some of today’s encryption. However, nothing is stopping hackers from harvesting data now and decrypting it later once more advanced technology is available, including “cryptographically relevant” quantum computers. From that point of view, all data is already in the danger zone. The need for terrestrial data security in systems managed by banks and healthcare providers is apparent, but the information from satellites needs to be secured, as well. Satellite information has been shown to be at risk using off-the-shelf satellite dishes and television equipment. With more than 12,000 satellites in orbit, serving government, military and commercial applications that span everything from powering weather forecasts to supporting our national defense posture, the importance of securing space-generated data is growing more vital by the day. “Communications and orbital computing are rapidly becoming critical infrastructure in space,” said Dennis Gatens, president of LEOcloud at Voyager. “Before, data was generated in space and brought back to Earth to analyze. Now, it’s happening on-orbit and it’s important to maintain the integrity and security of that data,” This is why Voyager, in collaboration with IBM, is charging ahead of the industry and proving the capability to deliver post-quantum security in space,today. Setting the Post-Quantum Standard In 2024, the National Institute of Standards and Technology (NIST) published their first batch of PQC standards.

It was a day of remarkable gains and technological milestones for the quantum computing sector on April 14, 2026, as IonQ, a leading player in the field, stole the spotlight on the New York Stock Exchange. The company’s shares surged by over 20%, closing at $35.76, after a series of groundbreaking announcements and a major contract win from the U.S. Defense Advanced Research Projects Agency (DARPA). The excitement didn’t just stop at IonQ. The entire quantum ecosystem, from hardware pioneers to AI integrators, was swept up in a wave of optimism, with investors and experts alike pointing to a new era for this once-niche technology. According to Benzinga Pro and TopStarNews, IonQ’s stock opened at $31.78 and saw robust trading throughout the day, fluctuating between $31.06 and $35.88 before closing near the day’s high. The trading volume was nothing short of extraordinary, with more than 68 million shares changing hands and a total trading value reaching $2.34 billion. This brought IonQ’s market capitalization to a hefty $13.1 billion (about 19.3 trillion Korean won), cementing its status as a heavyweight in the computer hardware industry. While the current share price stands well above its 52-week low of $23.49, it still has some way to go before reaching its 52-week high of $84.64. Financial indicators showed an earnings per share (EPS) of -2.25 and a price-to-book ratio (PBR) of 3.41, reflecting both the promise and the volatility inherent in this rapidly evolving sector. The catalyst for this surge was IonQ’s announcement that it had secured a coveted contract under DARPA’s Heterogeneous Architecture for Quantum (HARQ) program. As reported by Benzinga, the HARQ initiative aims to develop high-speed quantum interconnect technology capable of linking different types of quantum computers—trapped ions, neutral atoms, and superconducting qubits—into a unified network.

Thin films might not come up in conversation every day, but they are all around us. Take the metallic plastic films of chip bags, for example, or the anti-reflective coatings on eyeglasses. Even the coatings on pills that make them easier to swallow are thin films. Depositing extremely thin layers of materials in a consistent and uniform way is also crucial to the production of semiconductors, which are the foundation of modern electronics. Not all materials can be easily deposited in such thin layers, such as materials with very high melting points. Now, Caltech researchers led by Austin Minnich, professor of mechanical engineering and applied physics, and deputy chair of the Division of Engineering and Applied Science, have demonstrated a laser-based method for generating thin films of materials, such as niobium. The work could directly impact superconducting electronics used in quantum computers. The team recently described the work in a paper in the journal Applied Physics Letters. A common route to producing thin films is to heat the source material up to a high enough temperature that it produces vapor, which then condenses on the growth surface to produce a thin film. But materials that contain certain elements that scientists refer to as "ultra-refractory" will only melt above a scorching 3,000 Kelvin (2726.85°C). "If you think of your coffee cup with vapor coming off, it's the same idea except, let's say, you're doing it with tungsten. Now your coffee would be at something like 3,600 Kelvin," Minnich says. "What kind of cup is strong enough to withstand 3,600 Kelvin?" The answer is there isn't one. That is why it has been extremely challenging to create thin films of such ultra-refractory materials through the typical thermal evaporation route. But thanks to developments in laser technology for metal welding and cutting, a

IQM Quantum Computers has announced the implementation of AI-driven agentic calibration, a system designed to automate the tuning of superconducting quantum processors using the NVIDIA Ising open model family. Revealed on World Quantum Day, this development aims to eliminate the “manual bottleneck” of sequential calibration by using visual AI agents to inspect and tune multiple qubits simultaneously. This parallelized approach is intended to make quantum systems operationally viable for high-performance computing (HPC) data centers and “AI factories” by reducing the requirement for on-site quantum engineering specialists. The core of the architecture utilizes NVIDIA Ising Calibration models, which are fine-tuned to interpret measurement plots and adjust hardware parameters in real-time. This automation shifts the maintenance burden from human experts to intelligent agents, addressing the global scarcity of quantum talent that has previously hindered the deployment of on-premises quantum infrastructure. According to Juha Vartiainen, Co-founder of IQM, the goal is to allow enterprises to focus on application-level results rather than the underlying infrastructure maintenance. This collaboration builds on the existing integration between IQM and the NVIDIA quantum stack, specifically the NVIDIA NVQLink hardware interconnect and the CUDA-Q hybrid software platform. By integrating AI agents directly into its calibration infrastructure, IQM aims to maintain higher algorithmic efficiency and consistent high-fidelity performance across its superconducting QPUs. This production-focused strategy is designed to provide institutions with the capability to own and operate quantum systems at scale, bridging the gap between experimental laboratory setups and industrial-grade computing environments.

Bitcoin developers are trying to build quantum defenses. Your coins could pay the price. A proposal has been updated on Bitcoin's official repository, calling for freezing of quantum-vulnerable coins. What to know: - The BIP-361 would require bitcoin holders to migrate their coins to quantum-resistant addresses or risk having them permanently frozen by the network. - The plan, prompted by warnings that future quantum computers could crack Bitcoin’s current cryptography, would phase out vulnerable address types over several years and ultimately invalidate legacy ECDSA and Schnorr signatures. - The proposal has sparked backlash from parts of the Bitcoin community, who argue that freezing coins violates the cryptocurrency’s core promise of sovereign, permissionless control, while developers frame it as a necessary defensive measure. Bitcoin That promise is now, for the first time in Bitcoin's 16-year history, being challenged from the developer community itself, as a part of measures to build defenses against future quantum computers that could compromise Bitcoin's blockchain and steal your coins. The proposal Jameson Loop, one of the outspoken bitcoin contributors, and other cryptographers, have proposed a move that could force bitcoin holders to migrate their coins to new quantum-resistant addresses or face having their coins frozen permanently by the network itself. In that scenario, holders would technically still “own” the coins, but lose the ability to move them. It is called Bitcoin Improvement Proposal (BIP)-361 and was updated in Bitcoin's official proposal repository Tuesday with the title "Post Quantum Migration and Legacy Signature Sunset." This comes as a recently released Google report warned that a sufficiently powerful quantum machine could require significantly less firepower to compromise the Bitcoin blockchain than initially estimated. This prompted some observers to cite 2029 as the quantum deadline for bitcoin. To understand the need to freeze coins, you need to know what

How Columbus is leading the way on World Quantum Day - World Quantum Day is an annual observance on April 14 to highlight the science shaping the future of technology. - The Ohio State University has become a major player in quantum research, positioning Columbus as a technology hub. - The university has also launched one of the nation's first graduate programs in quantum information science and engineering. It's World Quantum Day, an annual global observance meant to spotlight the science shaping the future of computing, communications and cybersecurity. While the April 14 observance began as a grassroots effort to raise public awareness around quantum science, researchers say it now comes amid a broader global push to mark roughly 100 years since the birth of quantum mechanics. In Columbus, the day underscores the work that has helped make Ohio State University a major player in quantum research and central Ohio a growing hub for next-generation technology. At the center of that work is Ohio State's Center for Quantum Information Science and Engineering, known as CQISE, co-led by Ezekiel Johnston-Halperin, a physics professor, and Ronald M. Reano, a professor of electrical and computer engineering. The center brings together researchers across physics, chemistry, mathematics and engineering to advance work in quantum computing, sensing, networking and secure communications. Johnston-Halperin said the field is now entering what researchers call a second quantum revolution, one centered on how quantum information can reshape the same kinds of systems people already rely on every day— computers, communication networks and sensors. "The name uses the word 'information' the same way we use the word in 'information technology,'" Johnston-Halperin said, referring to computers, networks and digital sensors. "What the field is discovering is that there’s a second quantum revolution about how quantum mechanics can fundamentally affect those areas of
