Classical computers, running a newly developed algorithm, can now match and even exceed the simulation capabilities of some existing quantum devices. It means the simulations can be run using around five percent of the computing power previously needed to perform them with a supercomputer, the team says. This advance promises to lower the cost and accelerate research into building more reliable quantum computers, particularly those using light-based technology. Raul Garcia-Patron Sanchez of the School of Informatics. The new algorithm enabled classical computers to match the simulation performance of some existing quantum devices, a surprising result given the expectation that quantum hardware would inherently outperform classical systems in these tasks. This shift in capability has implications for the development of photonic quantum computers, a specific architecture benefiting from the ability to run more detailed simulations.

Researchers at Google Quantum AI and Cornell University have demonstrated a new error mitigation technique that surpasses existing methods by operating entirely in classical post-processing. Their work introduces virtual error cancellation, a method that reduces sampling overhead by using only syndrome records from quantum circuits, bypassing the need for prior noise characterization and modified circuits. Numerical simulations using a distance-7 rotated surface code show the full-stack dual-decoder algorithm achieves more than three orders of magnitude of suppression in error rate compared to standard decoding. This approach operates entirely through classical post-processing, offering a streamlined pathway to more reliable computation. The core of this advancement lies in the ability to avoid the typical requirements of noise learning and circuit alterations, both of which add complexity and overhead to quantum error mitigation.

The technical groundwork for a quantum-resistant internet is further along than the policy needed to build it. The IETF finalized the standard for encoding ML-DSA signatures within X.509 certificates in RFC 9881 in October 2025, yet as of this year the CA/Browser Forum has not approved their use in publicly trusted TLS certificates. This creates a clear timeline; organizations can begin building post-quantum certificate authorities now, but widespread adoption for secure browsing remains a future goal. Encryption, facing the immediate threat of “store now, decrypt later” attacks, prioritized key exchange solutions before signature updates. This discrepancy highlights a growing gap between the readiness of post-quantum cryptographic algorithms and the policy frameworks needed for their widespread deployment, a situation that could delay the transition to a quantum-resistant internet. NIST’s finalized standards, FIPS 204 for ML-DSA and FIPS 205 for SLH-DSA, published on August 13, 2024, define distinct approaches to quantum-resistant cryptography, each with its own performance characteristics and ideal use cases.

For more than 50 years, humanity has used "leap seconds" to keep our clocks aligned with the rotation of the Earth. On Thursday, an international timekeeping body in France voted to do away with leap seconds and let the clocks slip until they're out of alignment by a full hour, which could take centuries or even millennia. The precise atomic time we use to track our days — developed in the 1950s and measured by tracking the natural vibrations of atoms — is slightly out of sync with solar time, which is based on the position of the sun in the sky relative to a specific location on Earth, because the planet's rotation has been gradually slowing. The leap second was introduced in 1972 as a way to correct the discrepancy. Ten seconds were added immediately, says Scott Beattie, lead of the frequency and time team at the National Research Council of Canada's Metrology Research Centre. Since then, the International Earth Rotation and Reference Systems Service, which tracks the difference between the solar day and atomic time, has monitored the discrepancy to determine when an extra second is needed.

Hermès introduced the H08 collection in 2021 as a different take on the sporty-chic watch, first launched as a time-and-date series, then updated with a monopusher chronograph and, more recently, a skeleton model. The H08 stands out for its rounded square case, original Arabic numerals on the dial, and a mix of surfaces and materials that feels more considered than technical. Since then, the H08 has embraced titanium and ceramic, and in 2023 added references in a lightweight braided glass-fibre case coated with aluminium and slate powder, with concrete-grey dials and bright colour accents. The two latest editions keep the same recognisable silhouette and materials-led approach, bringing new colours. These new H08 models retain their thin 39mm cushion-shaped case with softly rounded edges, measuring 10.6mm in height. The case is made from braided glass-fibre composite with an aluminium-coated surface, delivering a brighter colour than the previous slate-coated editions. The material’s interwoven structure gives it a distinctive appearance, while its lightweight construction suits the watch’s character.

Zócalo executive director Moira Shourie's Fitbit accompanied her for almost 18 years, capturing heartbeats, steps, and rest cycles—but missing milestones along the way. Shourie explains why it's time to say farewell to the fitness tracker. | Shourie and her son at the Palisades 4th of July Run in 2009. Credit: Moira Shourie I’m breaking up with my Fitbit. I’ve worn this little device on my wrist while it silently kept an uninterrupted record of my pulse and sleep patterns for nearly 18 years. Intertwined with my heart rate data are moments of anxiety, anticipation, pure joy, and intense heartbreak.

Space technology is bringing civil protection and defence closer together. As geopolitical tensions rise and extreme weather events place increasing pressure on emergency services, the boundaries between civil protection and defence are becoming an important topic for the space and technology sectors. Technologies originally developed for civilian applications are increasingly relevant to defence, raising questions about how they can be adapted, funded and deployed responsibly.

Set Trending Topics as a preferred source on Google. Anyone waiting for the one quantum computer that will replace every classical machine will be disappointed by Jan Henrik Leisse. The chief executive and co-founder of eleQtron has little time for grand promises, even though his company is among Europe’s best-funded quantum start-ups. The spinoff from the University of Siegen raised a €57 million Series A, led by Schwarz Digits, the I. T. arm behind Lidl and Kaufland, and the EIC Fund. Instead of lasers, eleQtron uses microwaves to control the ions in its quantum computers, and together with the Research Fab Microelectronics Germany, the company is building its own chip production.
