Worried about how online firms use data they get from you? Berkman Klein researchers unveil new tool to verify identity, let users limit information they share, where it is stored In our increasingly online lives, convenience has come at a cost. The average person has more than 100 online accounts, and creating a new one often requires handing over personal information like an email address or a birthdate. Researchers at the Applied Social Media Lab at the Berkman Klein Center for Internet & Society say the current system puts your privacy at risk and makes you more vulnerable to identity theft, and they have a plan to fix it. As part of a digital identity symposium in April, engineers from ASML launched the Keyring wallet, an open-source identity verification tool. Rather than surrendering personal data to be stored in corporate databases, Keyring lets users keep their information on their mobiles and disclose only what is absolutely necessary to verify who you are. “Identity is actually deeply personal,” said ASML principal investigator James Mickens, Gordon McKay Professor of Computer Science at Harvard John A. Paulson School of Engineering and Applied Sciences. “Your age, your name, your location, your gender — all of these are inextricably tied to you as the user, not to some company or some particular piece of technology.” “We were handed a problem nobody had solved. We had no UX patterns, no templates, no precedent. And we built something that a real person can pick up and use in seconds.” Nicole Brennan, senior UX designer During the symposium, researchers described what they see as an increasingly insecure digital identity ecosystem. Meg Marco, senior director of ASML, said individuals have too much data spread out over too many accounts they don’t fully control. “This is important, not only because
05.01.2026|Dan Robinson An attacker with a powerful enough quantum computer could steal hundreds of billions of dollars of Bitcoin. To prevent that, the Bitcoin community may someday choose to upgrade the protocol to sunset the ability to spend from addresses with exposed public keys. Such an upgrade would be controversial, in part because Bitcoin values the rights of dormant holders—including Satoshi Nakamoto himself, who is estimated to hold around $75 billion of Bitcoin in vulnerable addresses—to remain inactive onchain. If an upgrade sunsets support for those addresses, these dormant holders will be forced to publicly move their coins or let them be frozen. But if quantum computers are coming and we don’t sunset those addresses, those holders will be forced to move those coins or let them be stolen. Either path seems to force long-time holders to give up some of their privacy by publicly moving their funds. This post proposes a way out of that dilemma, by letting Bitcoin holders protect themselves from any eventual sunset costlessly and silently, without having to publicly move their coins. The key is that holders can use Bitcoin itself to secretly timestamp their knowledge of their private keys. A future protocol upgrade could then accept zero-knowledge proofs of these Provable Address-Control Timestamps (PACTs) as an alternative path for spending from a sunsetted address. This protocol could protect the privacy and security of existing Bitcoin holders better than the alternatives. And adopting a standard for these proofs now would help give holders as much time as possible to secure their coins against an emergency sunset, while allowing us to leave the more difficult decisions—including whether a sunset is necessary or desirable—until later. Recent advances raise the question of whether cryptographically relevant quantum computers (CRQCs) could come sooner than most people had hoped. There are

Oxford scientists create rare quantum effect 100 times faster than expected It demonstrated quad squeezing at a pace that has left the scientific community reeling, achieving the effect 100 times faster than anyone thought possible. For the first time in quantum physics, Oxford researchers have demonstrated quadsqueezing, a complex fourth-order quantum interaction. The study introduces a novel method for controlling quantum harmonic oscillators — systems that mimic vibrating objects such as springs or pendulums at the subatomic level. It demonstrated quad squeezing at a pace that has left the scientific community reeling, achieving the effect 100 times faster than anyone thought possible. “The result is more than the creation of a new quantum state. It is a demonstration of a new method for engineering interactions that were previously out of reach,” said Dr. Oana Băzăvan, lead author from the Department of Physics, University of Oxford. “The fourth-order quadsqueezing interaction was generated more than 100 times faster than expected using conventional approaches. This makes effects that were previously out of reach accessible in practice,” Băzăvan added. The experiment setup Physicists have long used a trick called “squeezing” to sharpen the fuzzy measurements of the subatomic world. It is why gravitational-wave detectors, like LIGO, can hear black holes colliding across the universe. But for all its utility, ordinary squeezing is a relatively simple, second-order effect. Going higher — into the complex realms of trisqueezing and quadsqueezing — has long been dismissed as an experimental pipe dream. Until today. In a recent paper, a team led by Băzăvan and Dr. Raghavendra Srinivas announced the identification of out-of-reach quantum interactions using a single trapped ion. Two carefully controlled, simpler forces were applied to a trapped ion using a phenomenon called non-commutativity. In particular, researchers experimentally demonstrated quadsqueezing, a complex fourth-order quantum interaction previously considered
HIPAA's Security Rule meets quantum risk: A renovation that needs one more fix Proposed changes to the HIPAA Security Rule mark the biggest update to healthcare data security in a decade, but while the rule acknowledges emerging quantum risks, it stops short of fully addressing them. Contributors: Isha Singh CIPP/E, CIPP/US Attorney In January 2025, the U.S. Department of Health and Human Services issued a notice of proposed rulemaking to update the Security Rule under the Health Insurance Portability and Accountability Act, the most significant overhaul of healthcare data security obligations since 2013. While encryption standards currently used to satisfy the rule may not hold beyond 2030, and the U.S. National Institute of Standards and Technology has already published replacements designed for a quantum computing future. Discussions around quantum computing often swing between "not in our lifetime" and "everything breaks tomorrow." The reality sits somewhere in between. It is not here yet in a way that disrupts cybersecurity, but it is close enough that decisions made today will determine whether sensitive personal data remains protected 10 or 20 years from now. This matters because healthcare data is unusually long-lived. A credit card number expires. A genomic profile, clinical trial dataset or decade-long patient record does not. That changes how we think about data security under the HIPAA Security Rule and its proposed update. What is quantum computing, and why does it matter here? Classical computers process information in binary, as either zero or one. Quantum computers use qubits, which can exist in multiple states simultaneously. This allows them, at sufficient scale, to solve certain mathematical problems exponentially faster than any conventional machine. Modern encryption relies on those problems being effectively unsolvable. That assumption underpins widely used algorithms such as RSA-2048, which protect electronic protected health information across healthcare systems. Quantum
Anna Grassellino, chief technology officer and associate laboratory director for the Technology Directorate at Fermi National Accelerator Laboratory, has been appointed to the U.S. Department of Energy’s Office of Science Advisory Committee, known as SCAC — a federal advisory body that provides independent advice on scientific priorities and strategies. Grassellino will also serve as chair of the SCAC quantum subcommittee. In that role, she will help guide national efforts toward DOE’s 2028 goal for error-corrected quantum computers capable of addressing major scientific challenges. The subcommittee is also charged with exploring partnership opportunities and leveraging resources across the broad U.S. quantum ecosystem. These can include unique capabilities at national labs, innovations emerging in the private sector and resources across other federal agencies. SCAC provides guidance to the DOE Office of Science on major scientific and technical issues, including emerging opportunities and cross-cutting initiatives. The quantum subcommittee will assess the current state of quantum information science and identify the key steps needed to advance the field at the national level. “Anna brings a combination of scientific excellence, technical vision and leadership in large-scale quantum initiatives,” Fermilab Director Norbert Holtkamp said. “We congratulate Anna on this very important appointment and will fully support the committees and her work.” Grassellino is an internationally recognized physicist and director of the DOE’s Superconducting Quantum Materials and Systems Center, a national quantum information science research center led by Fermilab. Her work has advanced superconducting technologies for both accelerators and quantum systems, including innovations that have enabled record performance and new capabilities in superconducting devices. “I am honored to serve on SCAC and to chair the quantum subcommittee,” Grassellino said. “This is an important opportunity to help define a clear path forward for quantum information science and to accelerate progress toward fault-tolerant quantum computing.” Fermi National Accelerator Laboratory
Building useful quantum computers ‘in our direct line of sight’ Researchers say creation of startups suggests game-changing tech may be developing at faster pace than expected Mihir Bhaskar was a self-described “total nerd” in high school. He volunteered at a computer history museum and became obsessed with the hardware and how it all came to be: from abacuses to punch cards, vacuum tubes to personal computers. “I was really fascinated with the history of computing, the development of the semiconductor and transistors and things like that,” said Bhaskar, who received his Ph.D. in physics from Harvard in 2021. Over the past decade, Bhaskar and other grad students, postdocs, and professors have made strides in developing quantum computing, work that one day may land their devices in a museum display. The pace of their progress has already fostered three startups, a sign the game-changing technology may be developing ahead of expectations, researchers say. “I have never seen a science that is so ‘blue sky’ go out into the commercial sphere so quickly,” said Evelyn Hu, Tarr-Coyne Professor of Applied Physics and of Electrical Engineering. “Where are we now compared to where we thought we’d be in 2018? We are so much farther ahead than I think any of us could have imagined.” One of the three startups, LightsynQ, was co-founded in 2024 by Bhaskar to commercialize his doctoral research in quantum networking. The company was acquired last year by publicly traded IonQ, where Bhaskar is now senior vice president for research and development. Another, QuEra, was founded in 2018 by Mikhail Lukin, co-director of the Harvard Quantum Initiative in Science and Engineering, and Markus Greiner, George Vasmer Leverett Professor of Physics, with partners from Harvard and MIT. QuEra recently shipped its second commercial quantum computer — based on technology from their
Quantum technology startup QMatter raises $1.2 million QMatter’s current focus is the life sciences market, working with pharmaceutical and biotechnology companies to accelerate R&D by enabling better simulation data and ultimately improving research outcomes. QMatter, a Boston- and London-based startup, has raised USD 1.2 million in pre-seed funding, led by 55 North, a pure-play quantum fund, with participation from XTX Ventures, Bellstate Oy and the Conception X Angel Syndicate. The company will use the capital to further develop and scale its quantum compression platform, QMatter said in a media release. QMatter’s current focus is the life sciences market, working with pharmaceutical and biotechnology companies to accelerate R&D by enabling better simulation data and ultimately improving research outcomes. In parallel, the company is generating high‑quality, physics‑informed data libraries, creating new opportunities for machine learning companies to train next‑generation AI models using previously unavailable, problem‑specific data, the media release said. QMatter’s quantum compression technology applies principles from quantum mechanics to reduce the size of a problem before it is run on a quantum or classical system. The approach is designed to extend what current, near-term and future quantum computers can handle, while also accelerating classical algorithms at every scale, from consumer hardware to large supercomputers. “QMatter compresses complex quantum problems to their essential core, ensuring solutions remain both accurate and useful,” said Dr. Alexis Ralli, Co-founder & CEO, QMatter. “By doing so, we unlock greater performance from today’s quantum hardware while broadening the problem landscape for future error-corrected machines.” “Quantum computing promises to be transformational for the hardest problems we face, but the full value remains unrealized due to real-world limitations that constrain the size of problems we can address today,” said Dr. Tim Weaving, Co-founder & CTO, QMatter. “This investment will support the continued development of our quantum compression platform.”

Normally, when you design an electronic gadget, you worry about how hot it will get. Automotive-grade components, for example, often have higher allowable temperatures than commercial parts. However, extremely cold environments, such as deep space or the interiors of quantum computers, are also challenging. Researchers at King Abdullah University of Science and Technology believe gallium oxide may be key to operating near absolute zero. According to [Vishal Khandelwal], one of the researchers, most conventional electronics fail below -173C or 100K. Quantum computers routinely operate at 4K. However, β-Ga2O3 is a wide-bandgap semiconductor that has low current leakage and works at high temperatures up to 500C. However, it also avoids the freeze-out effect that traps electrons in other semiconductor materials. The team built two devices from the material seeded with a silicon dopant. The first was a FET with a fin-shaped geometry. The second was an inverter. Both operated reliably down to 2K. Gallium oxide has many interesting properties. For that matter, so does gallium.

Mind the Gaps: Quantum Optimization for Efficient Electric and Autonomous Freight Dispatch with IonQ and Einride The shift to electric freight is accelerating, and its economics hinge on a planning problem that conventional routing software was not designed to handle. Research conducted by Einride, a technology company building the infrastructure for electric and autonomous freight, alongside Fraunhofer and Rewe, found that optimizing electric fleet operations from the ground up reduced fleet-level total cost of ownership by 8–13%, compared to roughly 3% for straightforward 1:1 replacement of diesel trucks with EVs. Electric fleets introduce charging schedules, energy constraints, and route interdependencies that make planning substantially more complex than conventional trucking. That complexity, managed well, is where the economic advantage lives. That optimization advantage depends entirely on how well the plan holds, and how well the system recovers when it doesn't. Einride operates its fleet through Saga, an AI-powered platform that connects vehicles, infrastructure, and data to manage freight operations at scale. Shipment cancellations are a daily feature of large-scale logistics, leaving idle gaps in pre-optimized vehicle schedules that directly erode the fleet utilization rates that make electric freight economically viable. Einride's fleet operations team deals with them continuously, using its Electric Vehicle Routing Problem (E-VRP) solver to slot in replacement shipments from a waiting pool. Each gap carries hard constraints: vehicle charging limits, driving time regulations, time windows, and driver shift boundaries. The solver is fast and effective for individual gaps. What it does not naturally account for is the interaction between gaps on different vehicles: how two replacement shipments assigned to nearby routes might conflict operationally, create scheduling dependencies downstream, or compound risk across the fleet when executed together. That interaction between concurrent assignments is where classical gap-filling solvers are structurally limited, and where the quantum formulation is specifically designed
On April 14, Nvidia released open-source artificial intelligence models called Ising, designed to address two major engineering challenges in quantum computing: processor calibration and real-time error correction. By targeting key barriers to scaling quantum systems for AI, Nvidia’s move boosted confidence in the field’s potential. Following the announcement, Xanadu’s stock surged about 250% to a peak of $32.67 per share. Before that, it had traded below $10 since going public in March. The stock closed just under $8 in the session before Nvidia’s announcement, according to financial site The Street. With a 15.6% stake, Weedbrook’s net worth jumped to around $1.5 billion within five days, Bloomberg reported. Although the share price has since eased, it remains more than double its pre-announcement level. | Christian Weedbrook, founder of quantum computing firm Xanadu. Photo from X | Weedbrook’s path to billionaire status is unusual even in the tech industry. Born and raised in bushland southeast of Brisbane, Australia, he initially aimed to become a filmmaker but dropped out of film school twice. At 23, while working part-time in a video store and stocking groceries, he decided to go back to school and study mathematics, a subject he had performed well in during high school. "I’d exhausted every other option," Weedbrook, 49, told Canada’s The Globe and Mail. "I thought ‘I’ll just go back to something I was okay in – math. I don’t know where this will head, I’ll just see.’" At the University of Queensland, where he enrolled, administrators were skeptical. One dean even asked to check his arms for track marks, suspecting drug use. The decision to enroll proved pivotal, as the university was a leading center for quantum optics, the study of how light behaves at extremely small scales. Weedbrook later earned a doctorate in physics specializing in quantum
The University of Utah convened faculty, students, postdoctoral scholars, industry partners, and national leaders in science and engineering for its Quantum Science & Technology Symposium on April 24 in the Crocker Science Center. The daylong event highlighted the university’s growing momentum in quantum research and its commitment to building interdisciplinary collaborations in one of the most strategically important fields of the 21st century. Collaboratively organized by the Office of the Executive Vice President for Academic Affairs, the Office of the Vice President for Research, the College of Science, the John and Marcia Price College of Engineering, and the Quantum Research Working Group, the symposium brought together experts spanning quantum chemistry, quantum physics, and quantum engineering. The program was designed to connect the University of Utah community with world-leading researchers while accelerating new opportunities for discovery and partnership. Quantum science focuses on the behavior of matter and energy at the atomic and subatomic level, where particles can exhibit properties unlike anything seen in everyday life. Those phenomena are enabling new generations of technologies—from ultra-secure communications and powerful new computers to advanced sensors, precision timing systems, and novel materials with transformative commercial and national security applications. “Quantum science is reshaping what’s possible, driving new frontiers in innovation, strengthening our economy, and advancing national security. For Utah, this is a moment to lead,” said Taylor Randall, president of the University of Utah, “We are bringing together talent, partnership, and discovery to help define this next era and translate it into real impact for our state and beyond.” The symposium featured keynote presentations from three distinguished scholars: Ashok Ajoy of the University of California, Berkeley; Andrea Young of the University of California, Santa Barbara; and Scott Diddams of the University of Colorado Boulder. Their talks highlighted major advances in quantum sensing, advanced materials, precision
Groove Quantum, a Delft-based quantum computing startup developing scalable germanium spin-qubit processors, has raised €16 million in combined funding and unveiled an 18-qubit semiconductor spin-qubit processor, which the company says is the largest of its kind ever built. The round includes €10 million in equity co-led by Innovation Industries and 55 North, with participation from Verve Ventures and the European Innovation Council Fund. The remaining €6 million comes through grants from the EIC Accelerator programme and the EU Chips Act funding programme. “Quantum computing will only have real impact if it can be engineered and manufactured at scale. With this funding and our 18-qubit prototype, we’ve shown that semiconductor spin qubits are not just a promising idea. They are ready to scale rapidly, and we believe our approach gives us the best shot at reaching the million-qubit systems that will change the world. “We are building technology to be produced and deployed at global commercial scale, just as every substantial semiconductor technology before us,” says Dr Anne-Marije Zwerver, CEO and Co-founder of Groove Quantum. A quick analysis of 2026 activity shows several comparable quantum and adjacent DeepTech funding announcements alongside Groove Quantum’s €16 million raise. - Delft-based Orange Quantum Systems / OrangeQS raised €15 million to scale quantum chip testing infrastructure, making it the most directly comparable example by both geography and sector, as it is also based in Delft, Netherlands. - Dublin-based Equal1 closed a €51 million round to scale silicon-based quantum computing - Espoo-based IQM Quantum Computers secured €50 million to support quantum technology development and market expansion. In adjacent quantum-enabling hardware: - Münster-based Pixel Photonics raised €13.5 million to accelerate market entry for superconducting single-photon detector technology - Lausanne-based Rhonexum raised €867.5k to advance cryogenic electronics for scalable quantum computing - Tampere-based Vexlum raised €10 million to
IonQ has published a detailed blueprint for a fault-tolerant quantum computer, outlining a design it says could move the field beyond its current experimental limits and into practical use. The architecture, described in an arXiv preprint earlier this month by researchers including Felix Tripier and Nicolas Delfosse, lays out a full-stack system capable of running millions of quantum operations on hundreds of logical qubits. The company argues that its design relies only on hardware techniques already demonstrated in laboratories, positioning it as a near-term engineering challenge rather than a distant theoretical goal. Currently, most quantum computers fall into the category of noisy intermediate-scale quantum (NISQ) devices. These systems can perform thousands of operations, but errors accumulate quickly. Consequently, they struggle to solve problems of industrial or scientific importance. The IonQ team proposes a different approach. Instead of simply increasing qubit counts, it restructures the entire system architecture. Additionally, it integrates error correction, computation and hardware control into a unified design. At the core of the issue lies quantum noise. Every operation on a qubit introduces a small chance of error. Over time, these errors compound and degrade results. Fault-tolerant systems address this limitation by encoding information across many physical qubits. In this framework, a single logical qubit spreads its information across multiple physical units. Consequently, the system can detect and correct errors before they cascade. IonQ’s blueprint uses quantum low-density parity-check codes, or LDPC codes, to achieve this. These codes rely on sparse connections between qubits. As a result, they require fewer physical qubits than older approaches such as surface codes.

Scientists have achieved a major step toward chip-scale ultraviolet light by converting red light into powerful UV within a tiny photonic device. Ultraviolet light, beyond what comes naturally from the sun, plays a central role in modern technology, including sterilization, biological imaging, and chip manufacturing. Researchers also expect tiny sources of UV light on photonic chips to support future advances in quantum computing and ultra-precise atomic clocks. However, shrinking UV light sources to the chip scale has proven difficult because this light quickly loses strength as it travels through optical waveguides, limiting practical designs until now. A Harvard-led team from the lab of Marko Lončar, the Tiantsai Lin Professor of Electrical Engineering, has demonstrated a micron-scale photonic device built on thin-film lithium niobate that produces about 100 times more UV light on a chip than earlier methods. The study, published in Nature Communications, highlights lithium niobate as a promising platform for compact, efficient, and high-power UV generation. Instead of trying to directly guide UV light, the device generates it internally by converting red light into UV. This process, called frequency upconversion, combines two red photons inside the lithium niobate crystal, which is highly efficient at frequency conversion, to produce a single higher-energy UV photon. “Our group is perhaps best known for utilizing lithium niobate for photonic devices that operate at longer, infrared wavelengths – closer to the realm of telecommunications signals,” Lončar said. But he added that this transparent crystalline material, already widely used in integrated photonics, can also guide and generate shorter wavelengths such as UV. “When people think about [thin-film lithium niobate], they don’t think of it as a UV material, but we show that it is,” said co-first author Kees Franken, former research fellow in the Lončar lab. “We also show that there are some other nonlinear

Meta has already begun preparing for the threats posed by quantum computing and migrating its systems to post-quantum cryptography, a complex process that will take multiple years to complete. In a recent article, Meta researchers outline their strategy and share key lessons learned along the way. Meta describes its migration process as a far-reaching transformation of infrastructure, standards, and engineering practices across the entire organization. To track progress, they defined a five-level maturity model, from PQ-unaware to PQ-enabled, with the latter representing the ultimate goal of full quantum-resistant protection. Each level along the scale brings incremental protection. At the PQ-aware level, a company has assessed its usage of cryptography and understands what it takes to reach the next level, PQ-ready. PQ-readyness marks the beginning of the migration even if post-quantum secure solutions are not yet fully enabled. While this is not ideal, it would still make the company faster in reacting once an actual threat materializes. The strategy suggested by Meta's researchers is defined as a sequence of steps, beginning with prioritization. Companies should rank applications based on their vulnerability. In particular, systems that rely on public-key encryption and key exchange mechanisms are considered high priority, as these primitives are especially vulnerable in a post-quantum world. Among high-risk applications, we differentiate the ones that have no external dependencies (can be migrated right away), from the ones that have external dependencies and thus may need to wait until these dependencies are resolved. Medium- and high-priority applications are those that would only become vulnerable once actual quantum computer are available in the future. Among these, attacks on symmetric cryptography are considered low priority due to their substantial resource requirements (typically associated with brute-force Grover’s attacks, while applications relying on digital signatures are generally classified as medium priority Other steps in the process
