摘要
We consider a micromaser model of a quantum battery, where the battery is asingle mode of the electromagnetic field in a cavity, charged via repeatedinteractions with a stream of qubits, all prepared in the same non-equilibriumstate, either incoherent or coherent, with the matter-field interaction modeledby the Jaynes-Cummings model. We show that the coherent protocol is superior tothe incoherent one, in that an effective pure steady state is achieved forgeneric values of the model parameters. Finally, we supplement the abovecollision model with cavity losses, described by a Lindblad master equation. Weshow that battery performances, in terms of stored energy, charging power, andsteady-state purity, are slightly degraded up to moderated dissipation rate.Our results show that micromasers are robust and reliable quantum batteries,thus making them a promising model for experimental implementations.
