Abstract

In the context of quantum information, a quantum battery refers to a system composed of quantum particles that can store and release energy in a way that is governed by the principles of quantum mechanics. The study of open quantum batteries is motivated by the fact that real-world quantum systems are almost never perfectly isolated from their environment. One important challenge in the study of open quantum batteries is to develop theoretical models that accurately capture the complex interactions between the battery and its environment. the goal of studying open quantum batteries is to develop practical methods for building and operating quantum devices that can store and release energy with high efficiency and reliability, even in the presence of environmental noise and other sources of decoherence. The charging process of open quantum batteries under the influence of dissipative environment will be studied. In this Work, the effect of the classical driving field on the charging process of open quantum batteries will be investigated. The classical driving field can be used to manipulate the charging and discharging process of the battery, leading to enhanced performance and improved efficiency. It also will be showed that the efficiency of open quantum batteries depends on detuning between the qubit and the classical driving field and central frequency of the cavity and the classical driving field.
