Giant-Atom Quantum Batteries: Lossless Energy Transfer via Interference Engineering

Author(s): Ke-Xiong Yan, Yang Liu, Yang Xiao, Jun-Hao Lin, Jie Song, Ye-Hong Chen, Franco Nori, and Yan Xia Environmentally induced decoherence leads to irreversible energy loss during the active charging and discharging processes of quantum batteries (QBs). To address this issue, we propose a charging protocol utilizing the nonlocal coupling properties of giant atoms (GAs). In this Letter, both the QB an… [Phys. Rev.
