Open quantum systems traditionally demand defining both a system *and* its surrounding environment, linked by a prescribed interaction. This work bypasses that need, instead allowing the environment t…
A ten-fold performance gap separates leading quantum technologies, with transmon qubits routinely achieving relaxation times in the tens of microseconds while comparable gatemons plateau in the few-mi…
Can standard calibrations fully account for errors in superconducting qubits as they become more complex? Measurements of a three-level transmon reveal a pronounced asymmetry of 0. 204 between qubit s…
For a calculation demanding 10³ operations, the orbifold lattice now appears to be 10⁴ to 10¹⁰ times more expensive than any published quantum simulation method. Claims of exponential speedup for simu…

Existing methods for modelling charge transfer failed to accurately capture behaviour beyond simple diffusion. This work recovers the correct transport exponent for ballistic, superdiffusive and diffu…
One in twelve times, a zero-probability event was predicted by a recent thought experiment designed to expose flaws in quantum mechanics. Now, utilising the established principles of contextuality, th…
Bell’s theorem and causal inference, seemingly disparate fields, share a common mathematical structure previously unknown. Exploiting this equivalence delivers polynomial speedups for determining caus…
Can disordered quantum systems reliably produce predictable measurement outcomes, even with environmental noise? New theorems demonstrate that the counts of specific patterns within these quantum reco…
Could a mechanical resonator’s motion be cooled to its lowest energy state even when vibrating faster than the rate at which it loses energy to its surroundings. This loop-shaping technique now achiev…
Phonon isolation of 60 dB and photon-phonon conversion isolation of 40 dB have now been achieved by optimising synthetic flux and coupling rates. This surpasses previous methods by demonstrating nonre…
Topology-hiding connectivity-assurance for QKD inter-networking Until now, establishing secure connections between distant points in a quantum key distribution (QKD) network necessitated trust in inte…
Transversal logical multi-controlled-Z gates are now demonstrated on quantum low-density parity-check codes and locally testable codes with soundness Θ(1/(log N)2r−1), resolving a major outstanding ch…
Until now, standard quantum modelling struggled with sharply bent nanoscale wires, unable to accurately describe particle behaviour at points of extreme curvature. This work extends the confinement po…
A quantum key distribution network spanning 100 nodes can now be independently verified in under two and a half seconds, with a communication overhead of less than 70kB. This efficiency unlocks a new …
Until now, systematically comparing the Goos-Hänchen shift across different parity-time phases has remained an open challenge. This work demonstrates markedly enhanced lateral beam shifts in an unbrok…
The signal of a non-intuitive mixed state is 1. 7 times higher than that of a standard in-phase signal, demonstrating maximised signal strength in strongly coupled systems. This framework successfully…
Eigenstates typically localise at boundaries exponentially, irrespective of system size. However, a new mechanism demonstrates scale-free skin effect where localisation length *increases* with the sys…
A 12. 7% gain in classification accuracy, achieved by combining compressed image data with quantum processing, signals a new approach to collaborative medical diagnosis. This framework overcomes limit…
Semidefinite programming relaxations now extend to quantum spin systems on lattices up to 16x16, overcoming previous limitations restricted to smaller scales. This advance allows for the computation o…
Linear-optical experiments now demonstrate scaling of O(N −0. 983), an improvement over previous quantum sensing methods. Single-shot measurement learning retains the square-root entanglement gain exp…
Beyond the well-established Gaussian models, open quantum evolutions admitting closed equations for low-order moments are now demonstrably wider. This work constructs a systematic method for building …
A theoretical physics review, previously requiring months to translate into scalable Python codebase, was completed in under a day using a multi-agent workflow. This demonstrates a shift from utilisin…
After 17 years, a New York Times investigation identified Adam Back, 55, as the creator of Bitcoin, a cryptocurrency now powering a $2.4 trillion industry. The year-long probe traced clues from decade…
