Abstract

Although implementing shortcuts to adiabaticity (STA) in open quantum systems remains challenging due to the complex control schemes required for such systems, their powerful ability to rapidly steer the system toward target states and their widespread applicability in quantum technologies have motivated us to explore their potential in quantum energy storage. In this work, we employ STA techniques to charge an open quantum battery and demonstrate that the extractable work (Ergotropy) from such a battery can be significantly enhanced by several times compared to the case where the battery is charged using a time independent driving field. Our results pave the way for accelerating the dynamics of open quantum systems and suggest promising applications in the development of high-performance, stable quantum batteries.
