The hybrid architecture of Andreev spin qubits made using semiconductor–superconductor nanowires means that supercurrents can be used to inductively couple qubits over long distances.

A successful silicon spin qubit design should be rapidly scalable by benefiting from industrial transistor technology. This investigation of exchange interactions between two FinFET qubits provides a guide to implementing two-qubit gates for hole spins.

Frequency combs, which are important for applications in precision spectroscopy, depend on material nonlinearities for their function, which can be hard to engineer. Now an approach combining magnons and exceptional points is shown to be effective.

Quantum low-density parity-check codes are highly efficient in principle but challenging to implement in practice. This proposal shows that these codes could be implemented in the near term using recently demonstrated neutral-atom arrays.

Spatial dynamics can obscure epidemic trends from surveillance data, biasing reproduction ratio estimates over long periods. A spectral correction reweights incidence data to remove this bias, thus improving monitoring to inform response strategies.

Controlling orbital magnetic moments for applications can be difficult. Now local probes of a kagome material, TbV₆Sn₆, demonstrate how the spin Berry curvature can produce a large orbital Zeeman effect that can be tuned with a magnetic field.

Bart Verberck uses the musical cent as a pretext to touch on some of the intricacies of musical tuning systems.

Eighty years on from the publication of Erwin Schrödinger’s interdisciplinary analysis on the origin of order in living organisms — What is Life? — we look at how physicists and biologists are approaching the topic today.

The time has come to consider appropriate guardrails to ensure quantum technology benefits humanity and the planet. With quantum development still in flux, the science community shares a responsibility in defining principles and practices.

Measuring air temperature is far from a trivial task, as Andrea Merlone, Graziano Coppa and Chiara Musacchio explain.
