Dynamical blockade of a reservoir for optimal performances of a quantum battery
arXiv:2407.16471 · doi:10.1038/s42005-025-01993-7
Abstract
The development of fast and efficient quantum batteries is crucial for the prospects of quantum technologies. We show that both requirements are accomplished in the paradigmatic model of a harmonic oscillator strongly coupled to a highly non-Markovian thermal reservoir. At short times, a dynamical blockade of the reservoir prevents the leakage of energy towards its degrees of freedom, promoting a significant accumulation of energy in the battery with high efficiency. The possibility of implementing these conditions in quantum circuits opens up new avenues for solid-state quantum batteries.
