The authors employ single photons and linear optics to simulate a two-qubit quantum battery and investigate the relationship between the performance of quantum batteries and the amount of entanglement and coherence that arise during the charging process. The results show that entanglement is not always the most important resource to boost charging, while coherence plays a nontrivial role.
Inner products of pure states and their antidistinguishability

In this work, the authors provide a counterexample to an antidistinguishability conjecture of Havlíček and Barrett.
Observing single particles beyond the Rindler horizon

Measurements of variations of the Unruh thermal distribution allow accelerated observers to detect inertial particles beyond the Rindler horizon. This is in contrast with classical physics.
