IBM develops cooling system for future quantum computers. IBM introduces a modular deep-freezing system that expands the capabilities of quantum computers, aiming for fault-tolerant machines by 2029. Báo Khoa học và Đời sống•23/08/2026 IBM announced that it has deployed the first modular quantum refrigerator that can be interconnected to scale up to meet the cooling needs of hundreds of quantum chips. This system is capable of cooling down to -273.14 degrees Celsius, close to 0 ° K. This move marks a significant step as IBM aims to introduce large-scale fault-tolerant quantum computers by 2029, applying quantum error correction techniques to overcome interference in real time and perform tasks without interruption. Quantum computers promise to perform many large-scale calculations in much less time than even the fastest supercomputers currently available. Quantum bits (qubits) typically require extremely low temperatures, close to absolute zero (-273.15 degrees Celsius). Qubits operate inside ultra-low temperature chambers, but the complex structure of conventional refrigeration systems creates many drawbacks during operation. If all the qubits were placed inside this refrigeration system, the entire system would have to shut down if one of them malfunctioned. You may also like IBM has redesigned its existing deep-freezing system by switching to a modular form factor. IBM's groundbreaking cooling system solves the problem by providing engineers with specialized modules that can hold a limited number of chips. Connecting the modules together leverages the combined power of the individual quantum processors. Each refrigerator module is over 2.4m tall, 2.4m wide, and has a capacity of approximately 0.25m³, directly connected to a quantum processor via superconducting cables. This allows multiple quantum chips to communicate, share information, and work together within a larger computer. This change allows for the integration of denser data display and control wiring, simplifies connections between adjacent cells, and increases the

US researchers achieve major breakthrough in quantum data transmission through open air The first of its kind US wireless demo extends an existing 161-mile quantum network and allows secure communications In a breakthrough, researchers at Stony Brook University and Brookhaven National Laboratory transmitted information through the open air across 13 miles-a major milestone toward adding wireless links to New York’s pioneering quantum communication network. The experiment primarily sends quanta of light from Stony Brook’s Quantum Watchtower to Brookhaven’s Quantum Lighthouse in Upton and helps connect future quantum computers beyond the limits of fibre-optic cables. The experiment was initiated by using a laser to generate quantum states of light containing just a few photons. It was observed that the particles left a light-guiding region about 5 micrometers wide, which is less than one-tenth the width of a human hair. The current network footprint is 161 miles and connects eight nodes across multiple institutions on Long Island and in New York City. According to Stony Brook President Andrea Goldsmith, combining the wireless link with a metropolitan fiber network represents a major breakthrough toward a quantum internet of things to secure encrypted communication. Regarding the test, Lab Director, Brookhaven John Hill said it is a major effort to scale quantum networks for communications and sensing. Nonetheless, state officials maintained that quantum networking could support research, health care and sustainable super-computing at Stony Brook and Brookhaven so they can conduct shared scientific investigations on a larger scale.

Via 9to5google.com Google’s Willow quantum chip solves in under 5 minutes what would take supercomputers 10 septillion years CEO Sundar Pichai tempers the excitement, saying practical quantum computers are still 5 to 10 years away from reality Google Quantum AI’s latest processor, Willow, completed a benchmark computation in under five minutes. The same task would take Frontier, one of the world’s fastest classical supercomputers, an estimated 10 septillion years.

SEALSQ Corp (NASDAQ: LAES) is one of the few public companies built entirely around the threat of quantum computers. It was spun out of the Swiss security group WISeKey. It designs and sells the tamper-resistant chips that store digital keys, and it has rebuilt those chips around cryptography meant to survive a quantum attack. This is its commercial history, from a corporate carve-out into a standalone Nasdaq stock, to the QS7001 Quantum Shield, to a cash-rich push into satellites and quantum hardware. It is a factual company history compiled from regulatory filings, so it is reporting rather than investment advice. 1. A WISeKey spin-off. SEALSQ Corp was carved out of WISeKey International Holding, a Geneva security company. The two still share leadership, a campus and a roadmap, and Carlos Moreira chairs and runs both. 2. Public as NASDAQ: LAES. SEALSQ began trading on the Nasdaq under the ticker LAES on 24 May 2023, and it got there through a partial spin-off rather than a conventional initial public offering. 3. A pure post-quantum play. The company sells secure elements, the chips that hold the keys inside a connected device, and it has rebuilt them around the post-quantum algorithms that ordinary chips will need. 4. The QS7001 is the flagship. SEALSQ launched the QS7001 Quantum Shield in November 2025, a chip built to run the new standardised post-quantum algorithms inside small IoT and embedded devices. 5. Validated entropy, certification pending. SEALSQ says the QS7001 runs the algorithms picked by NIST, the United States standards body. The chip has earned a NIST entropy-source certificate. The company calls that a precondition for the FIPS and Common Criteria approvals it is still working toward. 6. Cash-rich and expanding.

Researchers now estimate that cracking current crypto-security systems may require as few as 500,000 qubits, a reduction by a factor of 20 from previous assessments. This finding significantly shortens the timeline for potential breaches affecting sensitive infrastructure like satellite controls, power grids, and financial institutions. The work by Ryan Babbush of Google Quantum AI and colleagues reveals that approximately 90% of current crypto-schemes rely on solving complicated polynomial equations based on elliptic curve cryptography, rather than factoring large integers. “Quantum technologies have been thought of as ‘over a decade away’ for a long time,” says Stephanie Simmons, a quantum researcher from Simon Fraser University in Canada, who was not involved in the new research. Reduced Qubit Count Accelerates Quantum Hacking Threat The threshold for cracking widely used encryption may be significantly lower than previously thought; new analysis indicates that approximately 500,000 qubits are now estimated to be sufficient to compromise current crypto-security systems, a reduction by a factor of 20 from earlier projections. The team verified the efficacy of their hacking algorithm with a zero-knowledge proof, allowing a cryptographer to independently reconstruct and validate the full algorithm, now publicly available. This method secures software authentication, electronic passports, and financial transactions for cryptocurrencies like Bitcoin and Ethereum, systems previously thought safe from near-term quantum threats. A classical computer would require billions of years to breach these systems, but Babbush’s team demonstrates a potential quantum shortcut, requiring a superconducting quantum computer with around 500,000 qubits and 80 million gates to complete the operation in under ten minutes. This speed is concerning because it could jeopardize cryptocurrency transactions that rely on the short-term public sharing of secret codes. Separate research from Oratomic, a quantum computing company, suggests an alternative path to a quantum hack, estimating that 26,000 physical qubits could achieve the same

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.

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
