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. Rigetti's largest customer represented 64% of revenues and another accounted for 16%. Management expects quarterly and annual revenues to fluctuate with contract mix, pricing, milestones and delivery schedules while development contracts and

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. The two work hand in hand: Classical systems prepare and move the data, and quantum systems solve the enormous matrix problems that would otherwise take years. But that handoff

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.

- Shifting from pilots to infrastructure - UAE grows local qubit hardware - Saudi and Qatar scale partnerships The UAE, Saudi Arabia and Qatar are investing heavily in quantum technology as they try to translate academic research and overseas partnerships into practical applications and greater technological autonomy. Quantum computing harnesses the behaviour of subatomic particles to tackle problems in chemistry, materials science and logistics that conventional computers cannot handle. The technology “has matured out of its validation stage and into nascent industrialisation”, according to a report this month by Noah Ramos, chief innovation strategist at Montreal-based investment research company Alpine Macro. Artificial intelligence still dominates the region’s investment agenda, with Gulf states announcing more than $300 billion of related infrastructure plans. Quantum investment, while significant, is difficult to quantify because many major initiatives do not disclose spending. The US and China are accelerating a “sovereign quantum race”, Ramos said. Malak Trabelsi Loeb, Dubai-based CEO of quantum technology consultancy Vernewell Group, said the region was shifting from experimentation towards physical infrastructure and early applications. “An ecosystem is emerging, while the formation of a sustainable regional industry will depend on the creation of locally retained expertise, intellectual property, specialised companies and recurring commercial demand,” she said. UAE builds from the qubit up A qubit – a quantum bit – is the fundamental unit of information in quantum computing.

IBM connected two large, ultracold cryogenic modules, clearing an engineering hurdle on the way to a much larger quantum computer. The new system tackles a practical problem facing efforts to scale quantum computing: how to keep growing numbers of quantum processors cold enough to operate while giving engineers enough space to connect them. IBM said its modular architecture could eventually link hundreds of quantum chips and support its plan to build IBM Quantum Starling, the world’s first fault-tolerant quantum computer, targeted for 2029. Fault tolerance aims to let a quantum computer continue operating reliably despite errors by detecting and correcting them. IBM said Starling would combine advances in error correction, processor design, decoding and systems engineering. “The successful connection and operation of these cryogenic modules signals a leap forward in that direction,” Jay Gambetta, Director of IBM Research and IBM Fellow, said in IBM’s announcement. Superconducting quantum processors operate at ultracold temperatures. IBM said its first two connected cryogenic modules jointly reached 4 Kelvin, roughly the temperature of liquid helium, in less than five days, then cooled to below 15 millikelvin. IBM said the larger enclosure also created more room for wiring. Each module’s vacuum enclosure offered up to 12 times more wiring space than the enclosures in its most widely used IBM quantum systems, according to the company. The additional space enabled more chip-to-chip connections within individual modules and between separate modules. The company designed the box-shaped modules to connect in a tight row. This layout created room to link separate quantum processors directly through IBM’s L-coupler technology. IBM said L-couplers allow separate quantum chips to share information, communicate and operate as parts of a larger quantum computer. This modular architecture also gives IBM a way to work on parts of the cryogenic system separately. IBM said the design

Intense light bent out of shape - ultrafast lenses made from gas Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- and x-ray pulse control for applications such as chemical reaction steering, quantum computing, and advanced spectroscopy methods for fundamental science. ● High-frequency (XUV) light offers unique insight into fundamental atomic processes, but control of light on microscopic scales in space and time remains a challenge ● Novel beam shaping technique: researchers demonstrate manipulation of XUV pulses spatially and spectrally ● Gas as a laser-controlled optical element: non-linear interactions in helium gas create an intensity-dependent refractive index near resonance – the gas acts like a lens or prism that can be turned on and off extremely fast. Controlling the Light The first known man-made lenses to manipulate light dates back to 700 BC: a nearly four-centimetre-wide rock crystal piece, manufactured around that time, was found in Nimrod, Iraq. And while the intended original function of this lens is not entirely clear today, it still shows that as early as this, humans were aware of the light-focusing properties of materials. An important application of this knowledge was the invention of microscopes, more than two millennia later, that utilised the optical properties of focusing glass lenses to explore the previously unknown microscopic world. With the invention of lasers and subsequently short, intense laser pulses, scientists are now able to produce high-energy light at extreme intensities for very short periods of time, enabling more precise material-processing options, but also opening further insights into microscopic processes. The shorter the wavelength of the light used, the shorter the pulses can be – and the more precisely we can peer into

Researchers at the CNRS, École polytechnique, and Université Claude Bernard Lyon 1 have developed a new approach to calculating quantum dynamics on Lie groups, overcoming longstanding challenges in handling noncommutative momentum spaces and compact directions within these complex mathematical structures. The work, detailed in a recent paper identified as CPHT-RR020.072026, builds path integrals, tools for determining transition amplitudes, by generalizing the familiar “sum over winding numbers” typically used for calculations on a circle to Lie groups. This advancement allows the team to compute semiclassical approximations of propagators and partition functions for Euler-Arnold systems, achieving accuracy up to and including two-loop order. The research continues a study initiated in a previous paper, aiming to better understand quantum systems with inherent symmetries found in areas ranging from rigid body dynamics to condensed matter physics. Quantum Dynamics on Lie Groups: Path Integral Construction Recent work, detailed in a preprint identified as CPHT-RR020.072026, addresses a longstanding challenge in quantum dynamics on Lie groups: properly accounting for noncommutative momentum space and the presence of compact directions. Researchers Mathieu Beauvillain, Blagoje Oblak, and Marios Petropoulos have constructed path integrals, essential tools for calculating transition amplitudes, specifically designed to overcome these hurdles, extending the applicability of quantum mechanics to a broader range of group-based systems. The team’s approach builds upon earlier studies, notably their own work initiated in a prior publication [1], and leverages a decompactification of the group onto its Lie algebra, a technique analogous to methods used for path integrals on a circle. A key innovation lies in how they handle compactness, achieving this through a sum over winding numbers in maximal tori, effectively generalizing the familiar summation technique typically employed for circular path integrals. These Euler-Arnold systems, described as nonabelian generalizations of free particles, are central to the research; their classical dynamics reduce to

Neutral-atom quantum computing firm Infleqtion plans to test a quantum sensing system in Colorado in 2027 that could help locate critical mineral deposits underground before exploration companies spend heavily on drilling. The company says its quantum gravity gradiometry (QGG) technology can detect extremely small variations in Earth’s gravitational field. Those changes can reveal differences in underground density and geological structures that may point to potential mineral deposits. The planned field demonstration will test whether the technology can provide useful subsurface information earlier in the mineral exploration process. Infleqtion is evaluating several possible sites in Colorado’s Third Congressional District, with the final location and timing still to be announced. If successful, the approach could give exploration teams another way to narrow down promising areas before bringing in drilling equipment. That matters because finding and developing domestic sources of critical minerals can be expensive, time-consuming, and uncertain. Quantum sensing sees underground QGG works by measuring tiny changes in gravity caused by variations in the density of material beneath the ground. Different geological formations produce different gravitational signatures, allowing sensors to build a picture of what may be below the surface. The technology does not replace drilling or existing geological surveys. Instead, Infleqtion says it could be used alongside established geological and geophysical techniques to identify areas that deserve closer investigation. More from Innovation See All That could change an early stage of mineral exploration, where companies must decide where to spend money collecting more detailed data and drilling test wells. Better information before drilling could help reduce the number of low-potential sites that move into more expensive exploration stages. “America cannot secure the supply chains it cannot see,” said Matt Kinsella, CEO of Infleqtion. “The first step toward mineral independence is knowing what you actually have.

SAXON Q is selling a very different kind of quantum computer SAXON Q, a spin-off from Leipzig University founded in 2021, has opened orders for two new systems: the SXQ128 and SXQ512. The company describes them as the first diamond-based nitrogen-vacancy, or NV-center, quantum computers to move beyond 10 qubits commercially. Both are designed to work at ordinary room temperature without cryogenic cooling, vacuum equipment or a specialized laboratory. SAXON Q says the SXQ128 is available now, while deliveries of the larger SXQ512 are scheduled to begin in the second quarter of 2027. That changes the physical picture of quantum computing. Instead of placing a processor inside a dilution refrigerator operating near absolute zero, the machine can be deployed in a normal environment. SAXON Q lists an operating range of roughly 18 to 27 degrees Celsius and says its systems can run from a standard 230-volt outlet. Its newer platform is designed for rack and edge deployment, bringing quantum hardware much closer to the physical infrastructure already used for conventional computing. There is an important caveat, though. Room temperature does not mean the machine is a quantum computer that suddenly behaves like a conventional server. The quantum processor still requires carefully engineered optical, microwave and electronic control systems. What disappears is the enormous cryogenic burden associated with several other leading quantum-computing architectures. That distinction is crucial because cooling is not merely an inconvenience. It is one of the major engineering obstacles to putting quantum processors into ordinary computing environments. The secret is hidden inside the diamond The heart of the system is a tiny diamond chip. SAXON Q creates nitrogen-vacancy centers inside the diamond lattice by introducing nitrogen atoms and vacancies into carefully controlled locations. A nitrogen-vacancy center consists of a nitrogen atom next to a missing carbon atom. The
