Abstract
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.
