Very recently great progress has been achieved for a new type of quantum device: quantum batteries (QBs) which are capable to be charged, to store energy and finally to transfer it to consumption centers and other quantum devices. We develop here our theoretical feedback control algorithm for charging Bosonic quantum batteries with two different topologies of interaction between the charger and the battery set: parallel versus collective transfer of energy. The model of QB is composed of non-mutually interacting elements (quantum harmonic oscillators) in a Markovian bath. The charger of such a battery is implemented via the field which is pumping the energy into the batteries. We study the control approach in the form of Kolesnikov’s target attractor to track (i.e. to drive dynamically) the charging power of the batteries. We discuss the pros and cons of the control models for different charging schemes; demonstrate their efficiency, robustness and stability. The proposed algorithms can be applied to other physical types of quantum devices: Dicke QBs and spin QBs.
