Nature Physics, Published online: 01 May 2024; doi:10.1038/s41567-024-02482-4As counterparts to optical frequency combs, magnonic frequency combs could have broad applications if their initiation thresholds were low and the ‘teeth’ of the comb plentiful. Progress has now been made through exploiting so-called exceptional points to enhance the nonlinear...

Nature Physics, Published online: 01 May 2024; doi:10.1038/s41567-024-02480-6A practical and hardware-efficient blueprint for fault-tolerant quantum computing has been developed, using quantum low-density-parity-check codes and reconfigurable neutral-atom arrays. The scheme requires ten times fewer qubits and paves the way towards large-scale quantum...

Nature Physics, Published online: 29 April 2024; doi:10.1038/s41567-024-02478-0Frequency 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.

Nature Physics, Published online: 29 April 2024; doi:10.1038/s41567-024-02479-zQuantum 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.

Nature Physics, Published online: 25 April 2024; doi:10.1038/s41567-024-02471-7Spatial 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.

Nature Physics, Published online: 22 April 2024; doi:10.1038/s41567-024-02487-zControlling 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.
