Supersolids combine superfluid and crystal order and their response to external driving remains unclear. Now it is shown that, in a dipolar supersolid, rotation induces synchronization of the crystal motion via vortex nucleation.

Nuclear spins in solid-state systems can have very long coherence times, which makes them attractive for use as qubits. Now a nuclear spin qubit device has been developed with all-microwave two-qubit control that has important performance benefits.

Previous work on the limits of quantum information processing has often assumed access to unlimited computational resources. Imposing a requirement for computational efficiency on entanglement theory substantially changes what is possible.

Exploring the spin-resolved Hofstadter spectrum in the presence of interactions is challenging. Now, a series of magnetic phase transitions are observed as individual Hofstadter bands are filled, allowing the exchange interactions to be mapped out.

Two decades ago this month, Nature Physics published its first issue. We reflect on the past and look into the future.

Names of measurement units often honour notable scientists and are seemingly immune to change. Richard Brown and Juris Meija explore the legacy of this tradition.

In our very first issue we published eight research papers, on topics ranging from condensed matter physics to atom interferometry. Two decades on, we look back at those works and hear from their authors.

In this comment, we consider how artificial intelligence tools are reshaping the way mathematical research is conducted and discuss how future developments of this technology will transform mathematical practice.

Improvements in qubit performance are essential for the development of large-scale quantum computing devices. Sustained progress requires a broad approach combining physics, materials science, and engineering mindsets.
