Achieving practical fault-tolerant quantum computing has been limited by inflexible architectures for managing qubits on constrained chips. Technical University of Munich researchers have developed RushHour, a dynamically reconfigurable lattice surgery system which allows algorithms to run efficiently on smaller hardware. This approach enabled 86% of benchmarks to execute successfully where previous methods required sharply larger processors. RushHour is a new system improving how quantum computers manage their resources during calculations. The team’s approach allows complex algorithms to run on smaller computer chips; this represents progress towards building practical quantum systems capable of tolerating errors. In tests against existing methods, the new system successfully completed computations where others failed entirely, demonstrating its potential for advancing the field. Technical University of Munich researchers unveiled RushHour, a system designed to improve resource management in quantum computers and bring practical fault-tolerant computing closer to reality. Current methods for managing qubits are often inflexible, requiring pre-allocation of resources which limits performance on smaller chips. The team’s approach dynamically rearranges these resources, akin to rearranging tiles in a mosaic to correct errors and complete the picture, allowing algorithms to run more efficiently. This dynamic reconfiguration also includes an ‘ancilla space’, best understood as extra workspace around a puzzle being assembled, providing temporary auxiliary qubits without impacting core data storage. In tests, 86% of benchmarks ran successfully using RushHour where existing systems failed. Dynamic lattice surgery enables substantial gains in qubit utilisation and computational speed Technical University of Munich scientists have successfully demonstrated their new ‘RushHour’ system runs 86% of quantum computing benchmarks where established methods fail completely. Previously, computations demanded chips 1.2 to 3.5 times larger than those now required. This breakthrough originates from dynamic lattice surgery, a technique manipulating qubits by rearranging them during calculations, achieved through a co-design between hardware and compiler software.

Google Quantum AI researchers have determined that breaking the core cryptography of various cryptocurrencies, secured by the secp256k1 curve, may require as few as 1200 logical qubits and 90 million Toffoli gates, a significantly lower threshold than previously understood. The team’s work elucidates specific vulnerabilities blockchain technologies face with the development of quantum computers and potential mitigation strategies. To ensure responsible disclosure, the researchers validated their findings using a zero-knowledge proof without revealing specific attack vectors. This analysis reveals that emerging “fast-clock” quantum computers could enable attacks on cryptocurrency transactions in the public mempool. Shor’s Algorithm Estimates for secp256k1 Bitcoin Attacks This represents a significant reduction in the estimated resources needed for a successful attack compared to earlier projections, bringing the threat of quantum decryption closer to reality. These architectures, the researchers note, could enable “on-spend” attacks targeting public mempool transactions, potentially allowing malicious actors to seize funds before they are confirmed on the blockchain. A key distinction highlighted in the analysis is the difference between fast-clock and “slow-clock” quantum computers, such as those based on neutral atoms or ion traps. The researchers found that circuits executing Shor’s algorithm on superconducting architectures, with a 10-3 physical error rate and planar connectivity, could complete the calculation in minutes using fewer than half a million physical qubits. This speed is critical because it suggests a viable attack window exists once sufficiently powerful quantum computers become available. The implications extend beyond Bitcoin, encompassing any cryptocurrency reliant on the secp256k1 curve for securing transactions. Technical solutions would benefit from accompanying public policy, and highlight ongoing efforts to transition to Post-Quantum Cryptography as a crucial step toward long-term security. Logical Qubit & Toffoli Gate Requirements for Quantum Attacks Estimating the computational power required to compromise existing cryptographic systems is a central challenge in the emerging

Quantum X Labs Announces Results From Its AI-Driven Quantum Error-Correction Program; Latest Results Generated Using Google’s Public Surface-Code Dataset From A Real Quantum-Hardware Experiment | Quantum X Labs Inc. QXL | 0.00 | | Quantum computers are highly sensitive to noise, and quantum error correction is widely viewed as a necessary foundation for scaling quantum systems from experimental demonstrations toward reliable, useful computation. QXL’s work is focused on one of the central challenges in this transition: developing AI-assisted decoders that can interpret quantum syndrome data efficiently and accurately, and that can continue improving as quantum hardware advances. The latest results were generated using Google’s public surface-code dataset from a real quantum-hardware experiment. QXL evaluated its updated decoder on a public surface-code configuration using the same cross-validation approach used for Google’s published decoder comparisons. In this test, QXL’s updated decoder demonstrated improved performance against matching-family benchmarks, including Google’s published correlated-matching and PyMatching benchmark results for the same configuration. Importantly, QXL’s model was trained exclusively on synthetic samples and was not trained on real hardware shots from the Google dataset. The result supports a key principle behind QXL’s technical roadmap: quantum error-correction decoders should not only perform well in controlled simulations, but should also be able to generalize toward real experimental syndrome data. This synthetic-to-real transition is a critical step toward practical QEC workflows that can support future low-latency and eventually real-time decoding. "These results are important because they bring us closer to the point where AI-driven quantum error correction can be evaluated against real hardware behavior, not only simulation," said Prof. Nir Sharon, Chief Quantum Technology Scientist at Quantum X Labs. "Our updated decoder improved performance against matching-family benchmarks in this experiment while training only on synthetic data. That is a meaningful validation point for our roadmap toward trusted quantum error

Quantum computing may seem like a technology of the distant future, but it's rapidly becoming a reality. There are many pioneers in this space that are developing it toward what they hope will be a practical and useful technology, and IonQ (IONQ +8.02%) is among the best. IonQ stock is also trading well below its all-time highs, making it seem like a great stock to buy now. The market is in a risk-off state, but if that flips, IonQ could rally to new highs, making today a perfect time to buy a company that's among the front-runners in the race to bring viable quantum computing technology to market. IonQ has a long way to go Quantum computing is possible, but at this stage, the results it generates are not reliably usable. Every quantum computer is built around qubits -- their fundamental units of data calculation -- which are incredibly sensitive to outside interference. Tiny amounts of "noise" in the system can cause qubits to change state, rendering the results of their calculations inaccurate. Because of this, error reduction and error mitigation are two of the chief challenges that every player in the quantum computing space is focused on. Right now, IonQ's technology is the best in the world at delivering accurate results. It boasts a 99.99% two-qubit gate fidelity measurement. But that's still a long way from the level of accuracy delivered by classical computers. IonQ is working to develop a fault-tolerant 10,000-qubit quantum computer, which it believes to be the minimum size necessary for a system that could reliably deliver a quantum advantage compared to today's supercomputers and achieve mainstream viability. Currently, its 256-qubit system is undergoing testing, and it's expected to be a huge step forward for early adopters.IonQ is also working with numerous customers and partners that

A team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University has accomplished something no one else in the country has done: they beamed particles of light carrying quantum information across 13 miles of open atmosphere between two institutions on Long Island. The transmission, which took place on August 19 at 12:26 a.m. ET, represents the first permanent free-space optical quantum link in the United States. At a ceremony two days later, DOE Under Secretary for Science Darío Gil cut a ribbon on the receiving telescope as photons arrived in real time from Stony Brook's Quantum Watchtower. The daytime demonstration proved the system works even when background light levels are high. How It Works Conventional wireless technologies like cell phones and satellites rely on radio frequencies to send data without physical connections. But radio is far too noisy to preserve the fragile states required for quantum information. The Brookhaven and Stony Brook team turned instead to optical light, sending photons through the air the same way astronomers collect light from distant stars. From the rooftop of Stony Brook's Health Sciences Center, photons exited an optical fiber just five microns in diameter and traveled 21 kilometers to Brookhaven's Quantum Lighthouse, a facility perched atop a seven-story building. Adaptive optics expanded the beam to 25 inches to match the receiving telescope's mirror, then focused it back down to enter another five-micron fiber on the other side. Deformable mirrors running at kilohertz frequencies compensated for atmospheric turbulence in real time. "People think of telescopes as tools for looking up into space, but the same technologies that allow astronomers to precisely collect and control light are essential for these quantum experiments," said Justine Haupt, Brookhaven's lead scientist on the project.

MIT and University of Ferrara researchers created a mathematical blueprint for designing distinguishable non-Gaussian quantum states. Researchers worldwide are working to develop quantum systems for sensing, communications, computing, and control that could outperform today’s technologies. A major challenge is creating quantum states that are stable, measurable, and easy to distinguish, since these states are the foundation of any practical quantum device. Quantum states have unique characteristics that make them attractive for advanced information processing. However, achieving both stability and distinguishability remains difficult. Recovering information from a quantum system depends on how well its quantum states can be distinguished, a property tied to orthogonality. Because no two Gaussian states (a widely studied class of quantum states) are orthogonal, some level of error is unavoidable when trying to tell them apart. Current quantum devices also remain stable for only fractions of a second and often rely on complicated methods to distinguish between quantum states. Researchers at MIT and the University of Ferrara have now developed a new technique for creating more easily distinguishable states, a step that could support the next generation of quantum technologies. The approach is detailed in a paper published in Physical Review A by Moe Z. Win and Peter L. Falb of MIT, together with Andrea Giani and Andrea Conti of the University of Ferrara. The researchers discovered a way to translate quantum states of light into algebraic varieties (a mathematical structure from abstract algebra), allowing the problem to be expressed as mathematical equations that can be solved more easily. Designing More Distinguishable Quantum States “Quantum systems can provide performance that is significantly better than classical counterparts,” Win says, “but this doesn’t come for free.” To build practical devices that generate and detect different quantum states, “one needs to carefully engineer the quantum states in which they encode

Africa has already secured a place in the global quantum science landscape. Researchers across the continent are contributing to advances in quantum communications, photonics, sensing and fundamental physics, while South Africa has established national programmes aimed at building expertise in the field. But as quantum science begins its transition from laboratory experiments to real-world technologies, some researchers argue that the next challenge is no longer scientific discovery. It is developing the engineering, fabrication and industrial infrastructure needed to transform quantum effects into practical devices. “Quantum technology in a general sense has three main pillars,” says Andrew Forbes, professor in the School of Physics at the University of the Witwatersrand (Wits). “Communication, sensing and computing.” Quantum communication is already among the most mature branches of the field and could see widespread deployment in the near future. Quantum sensing, which exploits quantum effects to make highly precise measurements, could find applications in mining, environmental monitoring, navigation and health care. Quantum computing remains the most visible area of quantum research, but large-scale machines capable of outperforming conventional computers on most real-world tasks are still under development. “There is no quantum computer that can outperform a classical computer yet,” says Forbes. For African researchers, that distinction suggests that the continent’s greatest opportunities may not lie in building the world’s first large-scale quantum computer. Instead, they may emerge from developing quantum sensors, communication systems, photonic technologies, specialised software and advanced materials that underpin future quantum industries. From science to technology That shift from theory to technology is increasingly reflected in international research. A recent study demonstrated how researchers could use an electron beam to create more than 40,000 precisely arranged defects inside a crystal lattice, pointing towards a future in which materials can be engineered atom by atom for quantum applications.1 For Neerish Revaprasadu, professor

Xuan Du Trinh, Stony Brook University Imperfections are unavoidable in quantum systems, so determining which tasks noisy entangled pairs still support is key. Until now, understanding how these capabilities diminish with increasing disturbance has remained fragmented. The researchers have definitively mapped ability-absence intervals and definitive thresholds for mixtures of maximally entangled qubits subjected to complex noise. They have precisely determined how different quantum capabilities, including entanglement and teleportation, are affected by disturbances in paired qubits. These entangled pairs can support various tasks; however, imperfections inevitably introduce noise that degrades their performance. This provides definitive boundaries for when abilities appear or disappear as noise increases within complex systems. Importantly, this offers a unified understanding of the degradation process enabling optimisation of resources used in emerging quantum technologies like communication networks and advanced computation. At Stony Brook University, researchers have mapped how well entangled pairs of qubits perform tasks despite inevitable imperfections. These linked particles exhibit what Einstein termed “spooky action at a distance”, sharing a connected fate regardless of separation. Understanding this degradation is vital for building strong quantum technologies such as communication networks and advanced computers because real-world conditions diminish effectiveness. The team now details precisely where those thresholds lie along a spectrum of mixed signals from entangled pairs, suggesting optimisation strategies may fully mitigate these losses and unlock the full potential of future quantum devices. Zero thresholds define total loss of entanglement and steerability under local noise Scientists have demonstrated that pure local noise impacting Bell mixtures results in zero thresholds for both the entanglement threshold and all four steerability thresholds; this indicates a complete loss of these quantum capabilities even with minimal disruption. Previously, any level of such noise would entirely eliminate these important properties within the system. The research details two distinct orderings defining definitive thresholds based

Stony Brook, BNL unveil new tech to enhance power of quantum computing They’re not your grandfathers’ lighthouses. Researchers at Stony Brook University and Brookhaven National Laboratory on Friday demonstrated the transmission of light particles containing quantum information in what they called a first-of-its-kind step in "extending the nation’s longest quantum network." The ability to link infinitely more complex quantum computers via specially designed quantum "lighthouses" such as those at Stony Brook and Brookhaven lab is crucial to aggregating their combined power, researchers said. The plan is ultimately to allow the computers to work together across the country to "tackle some of the nation’s most pressing scientific challenges," BNL said. The next stop involves linking a similar quantum lighthouse across Long Island Sound at Yale University. "The future of quantum information science will depend not only on what individual quantum computers and devices can do, but on our ability to connect them," Department of Energy Under Secretary for Science Darío Gil said at the demonstration at BNL Friday, calling it a "remarkable first" for the county. "This achievement opens a vital new pathway for connecting quantum systems across distances in ways that fiber can't achieve," he said, adding that the work will eventually pave the way for advanced quantum satellite connections. "Quantum capabilities become more useful when we can connect them," he said. To accomplish their work, researchers at BNL and Stony Brook powered up a laser to "generate quantum states of light," each with a few individual photons, the lab said. One of the researchers, Justine Haupt, described the elation she felt when the first photon signals crossed the 13-mile gap in darkness early Wednesday morning. Stony Brook sent the signals from its "Quantum Watchtower," located on the roof of the university’s Health Science Center. The photons left that device

No company blew an earnings call. No contract fell through. Quantum computing stocks are sliding anyway, and the culprit is sitting in the bond market, not the boardroom. Quantum computing stocks are getting hit because the bond market is making patience more expensive. According to Barron's, the 10-year Treasury yield reached 4.71% on Thursday as stocks sold off and investors worried about higher borrowing costs. That number is the story. IonQ fell 6.7% to $40.46 on Thursday, Weiss Ratings reported, and the rest of the pure-play quantum basket was under the same pressure. Rigetti, D-Wave and Quantum Computing Inc. don't need a company-specific disaster to fall on a day like that. They only need rates to rise. You don't need a finance degree to understand the hit. IonQ, Rigetti, D-Wave and Quantum Computing Inc. are long-duration stocks: companies whose valuations depend heavily on profits investors hope will arrive years from now. Not this quarter. Not next year. Years away. When a safe 10-year Treasury pays close to 4.7%, the market asks a harder question of every distant-growth story: why wait for uncertain cash when boring cash already pays? That question lands hardest on quantum. The technology may become important in drug discovery, materials science, security and optimization, but the public companies selling the story are still early in the commercial cycle. IonQ has real revenue and a more visible customer base than some peers, but it still trades on expectations more than present earnings. Rigetti and D-Wave are selling access to machines and systems while the market is still working out how large near-term demand really is. Quantum Computing Inc. is even more speculative. When rates rise, investors don't treat those differences kindly. They sell the whole group first. The selloff started before Thursday This wasn't one bad session coming

For decades, physicists believed that mixtures of two fundamentally different quantum particles, bosons and fermions, couldn’t form stable droplets when interacting strongly. Bosons are particles that like to crowd together (photons, for example), while fermions obey the Pauli exclusion principle, meaning no two can occupy the same state (like electrons). Their behaviors are so different that combining them into a single, self-bound state seemed impossible. Researchers at Monash University have now refuted that assumption. The study, led by PhD candidate Sam Foster, predicts that under the right conditions, bosons and fermions can form stable, self-bound ‘quantum droplets’. The droplets are held together not by normal forces but by the fine balance of quantum mechanics itself. A quantum droplet differs from a drop of water, held together by surface tension, in that it results from a balance between attraction and quantum pressure: the bosons and fermions attract one another, but the fermions produce a sort of pressure that stops collapse. What is obtained in this way is a perfectly balanced and self-contained droplet. Foster explained: “Quantum systems can behave in ways that seem impossible in our everyday world. We’ve shown that these two very different types of particles can balance each other perfectly to create a stable droplet that effectively holds itself together.” Physicists accurately measured the mass of the W boson Previous theories could only describe Bose-Fermi mixtures when the particles interacted weakly. But the Monash team developed a new approach that works in the strongly interacting regime, precisely where the most exotic physics emerges. This advance goes beyond predicting droplets, as it also shows a wide variety of quantum phases, some of which exhibit behavior similar to the liquid-gas transition. The prediction is not just theoretical speculation. The researchers argue that these droplets should be achievable in existing ultracold

RGTI's Q2 Revenues Soared 185.3% but Losses Widened: What Comes Next? Rigetti Computing, Inc. RGTI delivered a top-line beat in the second quarter of 2026 as on-premises quantum hardware sales accelerated. At the same time, higher research and operating costs pushed losses further into the red. The key question is whether that hardware traction can outpace the spending needed to improve fidelity, scale systems and support commercialization. Gross margin improved, but the operating loss widened, leaving the next large system delivery as an important test. RGTI's Q2 Revenue Beat Shows Hardware Demand Second-quarter revenues reached $5.1 million, up 185.3% from $1.8 million a year earlier and 4.7% above the Zacks Consensus Estimate. The increase came mainly from higher sales of 9-qubit Novera quantum computing systems and related products. Sales of quantum computers and quantum components contributed about $4.1 million of quarterly revenues. The first two 9-qubit systems delivered in 2026 went to commercial organizations, making on-premises hardware a larger part of Rigetti's revenue mix. Rigetti's Cost Growth Dulls the Revenue Surge Gross profit rose 286.6% year over year to $2.2 million as gross margin expanded about 1,120 basis points to 42.6%. The mix benefited from Novera system sales, which carry a higher gross-margin profile than collaborative research and professional services. The cost structure still dwarfed the revenue base. Research and development expenses increased 53.3% to $20.7 million, selling, general and administrative expenses rose 37.5% to $9.5 million and total operating expenses climbed 47.9% to $30.3 million. Operating loss widened to $28.1 million from $19.9 million. RGTI's Customer Mix Keeps Results Lumpy Customer concentration remained high in the quarter.

The Quantum Technology Already in Use by Federal Agencies Today Some federal agencies are already hard at work on projects that employ quantum computing. The Department of Energy, for example, recently announced its Quantum Genesis initiative, which will deploy the “world’s first fault-tolerant, scientifically relevant quantum computing capability.” Meanwhile, the Federal Aviation Administration is looking to industry partners to help shore up its defenses against quantum threats. CDW is working with mission owners at the Department of the Navy to solve large logistical problems with quantum computing. Shipbuilding, supply chain management and wartime acquisition readiness are, at their core, enormous optimization problems that quantum is well-equipped to solve. This could look like forecasting complex supply chains, mapping new routes if a conflict disrupts them or sustaining operations under pressure. While larger federal agencies and departments are already getting started on using quantum computing in their workflows, many other federal entities who may benefit from quantum are missing out on the technology due to lack of infrastructure or expertise. For Federal Agencies, ‘Quantum Readiness’ Means Infrastructure Readiness At present, most federal agencies are generally unprepared to place a quantum computer in their own facilities. That pipeline doesn’t yet exist, and it may never need to. This raises an important question: If the computer is somewhere else, how can federal agencies safely access the technology? The Energy Department and the Navy have not suddenly acquired a swathe of quantum computers; rather, the technology is delivered primarily through cloud environments. In other words, the principles of IT have not changed with quantum, and the new technology won’t make classical computing obsolete any time soon.

Post-quantum cryptography: Why organizations should prepare now Post-quantum cryptography: Why organizations should prepare now With post-quantum standards emerging and regulatory expectations evolving, organizations need to understand their quantum-related risks and prepare for a secure transition. event 20-08-2026 Share Quantum computing could unlock significant advances across science, technology and industry. At the same time, sufficiently capable quantum computers would undermine many of the public-key cryptographic methods that organizations rely on to secure communications, authenticate users and systems, and verify the authenticity of software. The challenge for organizations is no longer only when cryptographically relevant quantum computers will arrive. It is whether the systems, data and technology investments they rely on today can remain secure throughout a multi-year transition. That transition has already begun. Post-quantum standards are available, the EU has established milestones for a coordinated migration, and Traficom guidance emphasizes early, risk-based preparation. For many organizations, the immediate task is not to replace every cryptographic mechanism. It is to identify where vulnerable cryptography is used, understand which critical use cases depend on it, determine what must be protected first and avoid creating new cryptographic legacy. Cryptography is a hidden business dependency Public-key cryptography is an invisible foundation of the digital economy. Methods such as RSA and elliptic-curve cryptography support secure web traffic, virtual private networks, digital certificates, user and machine authentication, email security, electronic signatures and software updates. If these methods become vulnerable, the impact will extend beyond data confidentiality. Organizations could face risks to digital identities, the authenticity of digitally signed information and the mechanisms used to establish trust between systems. One significant concern is the integrity of software and firmware updates. If an attacker can forge a trusted publisher’s digital signature, the update process itself may become an avenue for compromise. The risk also begins before sufficiently capable quantum

Quantum computers are expected to transform many facets of science and industry over the next decade or so – but it’s very hard for most potential users to get their hands on one to find out what they can actually do with it. A new open-access facility opened in Queensland this week aims to change that. The A$10.5 million National Quantum Computing Testbed is located at the University of Queensland and is a collaborative effort led by research teams from the university and CSIRO. It will allow researchers from academia and industry to test new ideas on a real quantum processor in an affordable and fully open access environment. As such, it removes many of the barriers to innovation in this rapidly developing field. From bits to qubits Everyday classical computing, like the kind that runs our laptops or mobile phones, stores and processes data in the forms of bits. These are are binary numbers – for example, combinations of 0s and 1s. Each bit can be either 0 or 1 at any given time. Quantum computing, however, stores and processes information as quantum bits – otherwise known as qubits. These exploit special properties of quantum physics to create what are known as “superposition” states. At any instant each qubit can be 0 or 1, like a traditional bit – or it can be any combination of both 0 and 1 simultaneously, such as 30% 0 and 70% 1. This will allow quantum computers to process certain kinds of very large datasets extremely fast. In turn, they could generate new discoveries which address challenging problems across various fields, from medicine and renewable energy to cybersecurity and urban design.
