Potential Massive Twitter/X Data Breach 2025: Insider Threat Exposes 2.8 Billion Accounts Rescana

Less Talk, More Security: Cyber Lessons Learned from Munich Center for European Policy Analysis (CEPA)

The cybersecurity industry is obsessing over Anthropic’s new model, Claude Mythos Preview, and its effects on cybersecurity. Anthropic said that it is not releasing it to the general public because of…

Circuits for complex quantum calculations are typically limited by their size and intricacy. Now, an automated design framework has achieved the Full-CI limit for molecular hydrogen using shallower ci…

Testing whether a directed network possesses a specific property now requires substantially fewer steps thanks to a new quantum algorithm. Previously, classical methods demanded a number of queries sc…

Extending ground-state cooling beyond single dimensions, this work simultaneously cools six motional modes of two levitated nanoparticles. Previous methods achieved cooling along one, two, or three di…

An Area Under the Curve of 0. 995 now distinguishes successful from failed Belief Propagation decoding for quantum error correction, a performance eclipsing all previous syndrome-based prediction meth…

Calculating a seemingly intractable quantum effect has become surprisingly simple, with a two-loop correction now derivable from a one-loop calculation. This advance bypasses a computationally intensi…

Four or more interacting Rydberg atoms, previously unamenable to detailed analysis, now yield their dark-state secrets through an extended arrowhead-matrix method. This work bridges a gap in understan…

Can established semi-classical physics accurately describe systems where quantum effects dominate, or does it inevitably fail when entanglement becomes significant. Incorporating environmental decoher…

Three unitary operations can be distinguished globally, yet proving impossible to label locally using classical communication alone. This contrasts sharply with quantum states, where any subset can al…

Orthogonalised self-guided quantum tomography now achieves 99. 17% fidelity in simulations, a marked improvement over the 95. 2% attained with standard methods.

Divide et impera: hybrid multinomial classifiers from quantum binary models Previously, scaling quantum classifiers to recognise more than two classes incurred a computational cost proportional to the…

Before now, deepfake speech detection struggled to consistently differentiate authentic voices from increasingly convincing imitations. New models incorporating Quantum Vision theory achieve 94. 57% a…

Analysing the amplitudes of peaks in quantum wave mixing now reveals the statistical properties of light sources, moving beyond simple observation. Previously, such measurements relied on coherent ton…

Can a quantum battery initially at rest actually be charged by its surroundings? New findings demonstrate that dissipation, typically considered a loss of energy, can activate work extraction even fro…

Evaluating the performance of a weak-field homodyne receiver in quadrature phase-shift keying optical communication Moving beyond two-state encoding, this work demonstrates quaternary communication us…

Can established time series analysis benefit from explicitly identifying where quantum effects improve forecasting accuracy. A new methodology integrates quantum principles into ARIMA models, reducing…

Asynchronous quantum distributed computing now extends classical causality principles to entangled systems. Until now, implementing atomic global operations across quantum networks relied on assumptio…

Kirkwood-Dirac distributions, previously determined using complex heterodyne detection, can now be measured with simpler interference-based techniques. This shift offers a new, unified understanding o…

Detectors responding to quantum fields reveal a state dependent on the order of interactions, appearing at second order in perturbation theory. Previously, such distinctions relied on excitation proba…

Evaluating QAOA as a readily usable tool reveals its current performance falls behind the established Goemans-Williamson algorithm for the Max-Cut problem. This assessment differs from previous work b…

Sufficiency and Petz recovery for positive maps Until now, extending the Koashi-Imoto decomposition to all positive, trace-preserving maps remained an open problem. This work achieves that extension, …

Previously intractable high-temperature Gibbs states now mix in just $\mathcal{O}(\log(n/ε))$ time, even with external fields applied. This rapid preparation, coupled with proof of classical hardness …
