  • The formation of defects in numerous systems is believed to follow universal scaling laws arising from the Kibble–Zurek mechanism. Ulm et al.measure this scaling law for defects created in ion Coulomb crystals, confirming the predicted behaviour for a system of 16 ions.

  • It has been predicted that a quantum system in the presence of quantum friction (which describes creation of coherence in the instantaneous energy basis) violates the usual work fluctuation-dissipation relation. Here, the authors confirm this hypothesis using a trapped ion.

  • In presence of inter-system correlations, violations of the laws of thermodynamics become possible. Here, the authors develop a formalism redefining heat, work and thermodynamic laws in terms of quantum conditional entropy, which consistently generalize thermodynamics in correlated scenarios.

  • An approach based on quantum sensing, in which controlled quantum systems serve as precision sensors, has enabled measurement of the weak magnetic interaction between two electrons bound to two separate ions. See Letter p.376

  • Large language models (LLMs) are a new and powerful tool for solving specific physics problems. Here, the authors explore their capabilities in solving three problems of increasing complexity in quantum optics, finding that with appropriate prompts and careful feedback, a well-trained LLM can be used as an effective scientific collaborator.
