Abstract

Here we invent a model of a single-qubit based quantum battery (QB) in the form of quantum oscillator in a Markovian bath environment. The effective control (stabilization) over the charging power dimensionless characteristics is performed via Kolesnikov’s type feedback algorithm. This method makes the effective design of the control fields charging the battery; the corresponding control signals could be restored explicitly from the dynamical equations. The proposed algorithm is robust, it is stable under the perturbation of the initial conditions in the system and under the application of a relatively small external noise. This algorithm could be adopted also for different physical realizations of quantum batteries: Dicke QB, spin QB; and for all working stages of the quantum battery (charging, long time storage and the energy transfer to a consumption center or engine).
