Instability-enhanced quantum sensing now outperforms previous methods relying solely on quadratic interactions, even when instability rates are identical. This advance stems from enhanced short-time d…
A 24-nanosecond quantum gate operating with 99. 9% accuracy was achieved, defying the usual slowdown required for reliable calculations. This performance stems from a new coupler design which simultan…
Coherent feedback control of quantum systems now requires solving at most four Lyapunov equations, a simplification from the previous standard of two coupled algebraic Riccati equations. This new meth…
Can a quantum computer operate with guaranteed results from every calculation, rather than relying on probability? This work demonstrates deterministic controlled-NOT gates using light, achieving this…
Entangled quantum clocks now demonstrate a precision that scales linearly with the number of clocks used, a marked improvement over previous methods limited to a factor of √N. This new protocol utilis…
Coherence, the quantum property enabling superposition, is unexpectedly diminished during efficient prime factorisation using Shor’s algorithm. This work details how the algorithm simultaneously gener…
Ten to the power of five quantum memories and ten to the power of ten programmable beam splitters were previously thought necessary for quantum target ranging. Now, a new receiver architecture achieve…
A predictable inflation of actuator variance, induced by correlated sampling, reveals the limits of modelling digital laser stabilisation as a memoryless process. This work moves beyond approximations…
Until now, strong-field ionization relied on predictable light, limiting control over electron behaviour. Bright squeezed vacuum light, delivered with up to 10 \textmu J of energy, selectively amplifi…
Until now, simulating collisions between baryons and mesons required simplifying assumptions about fundamental forces. This work demonstrates the first real-time observation of entanglement between co…
Magnon harmonic generation in antiferromagnets has extended beyond third-order observations to now include signals up to the sixth harmonic. Unlike materials lacking spontaneous symmetry breaking, mag…
Perturbation theory for hydrogen-like ions has long relied on approximations, often limiting the accuracy of calculated energy levels and decay rates. Now, an algebraic method utilising so(4,2) symmet…
Eleven per cent of photons successfully completing a full transmission cycle represents a marked improvement over existing methods for secure communication. Current systems rely on drastically reducin…
Previously, spin relaxation times in perovskite crystals lasted only tens to hundreds of nanoseconds. Now, measurements reveal these states can be maintained for up to 2 milliseconds in mixed-A-site p…
Emergence of Non-Markovian Classical-Quantum Dynamics from Decoherence Until now, fully quantum systems undergoing decoherence lacked a clear connection to classical descriptions of gravity, leaving o…
Until now, suppressing degradation in quantum states demanded complex operations beyond standard optical tools. This work demonstrates a method mitigating loss in up to five sequential operations, con…
For alpha greater than one, the Petz-Renyi divergence now exhibits convexity, mirroring behaviour previously understood only for values less than one. This advance establishes a geometric understandin…
Can quantum information truly be transmitted through turbulent air without relying on simplified assumptions about the channel itself? A new model derives the Quantum MIMO channel directly from wave-o…
The fraud landscape has been changed by AI and cryptocurrency in a way that should concern organisations and individuals alike. Read more in my article on the Fortra blog.
An international law enforcement action led by the U.K.'s National Crime Agency (NCA) has identified over 20,000 victims of cryptocurrency fraud across Canada, the United Kingdom, and the United State…
