Researchers at Quantum Art in Ness Ziona, Israel have published findings detailing a new approach to trapped-ion quantum computing, a method that utilizes all motional modes of ion crystals to entangl…
Quantum Hardware Engineer Martina Matusko is building a neutral-atom quantum computer at planqc, focusing on atom trapping and advancing their technology. She moved to Munich after completing her mast…
Equal1 is integrating Q-CTRL’s Boulder Opal Scale Up software into its silicon quantum computers, enabling autonomous operation and simplifying maintenance of qubits. This partnership aims to deliver …
Lockheed Martin’s Skunk Works developed “Ghost Murmur,” a new CIA technology using long-range quantum magnetometry to locate a downed airman in Iran.
Thirteen nations—including Australia, Canada, and the UK—met at the Quantum Development Group (QDG) summit to boost collaboration on secure quantum.
Current quantum computing factored only 21, slower than a calculator, posing no immediate threat to Bitcoin.
Expert echolocators can sense objects with just two click-echo sets, according to research published April 6 in eNeuro. This science reveals how the brain rapidly accumulates auditory evidence, a proc…
Leiden University’s exhibition connects Heike Kamerlingh Onnes’ 1913 achievement—liquefying helium—to today’s quantum materials research, showcasing.
Can time-periodic driving reliably stabilise complex quantum states, or are they inevitably undermined by unwanted heating and preparation errors. A new approach demonstrates that coupling a driven qu…
Scaling relations, typically associated with continuous phase transitions, now emerge from the average fidelity susceptibility of stationary states as temperature decreases. This establishes temperatu…
Until now, applying Floer theory to time-dependent systems presented a fundamental barrier to understanding quantum solutions. Extending Rabinowitz Floer homology to non-autonomous Hamiltonians overco…
Until now, achieving both deterministic entanglement and in situ spectral programmability in a quantum node demanded a trade-off between efficiency and tunability. This design combines a nitrogen-vaca…
Quantum processors struggle to generate the data needed to fix their own errors, forcing reliance on imperfect simulations. PAEMS, a new error model, cuts correlations in qubit errors by up to 19. 5 t…
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…
