AI 中文摘要
量子电池已成为为量子技术供电的新一代有前景的储能装置。远程充电极具吸引力，因为它能最大限度减少充电器与电池之间的干扰，因此受到广泛关注。本文中，我们提出一种基于脉冲控制超导量子比特链的拓扑保护远程充电量子电池协议。通过动态调制脉冲介导的耦合，我们实现了从充电器到电池的拓扑保护能量传输。研究表明，该充电过程无能量回流，且对脉冲控制中的缺陷具有鲁棒性。此外，目标时刻电池中存储的能量可完全提取，且该协议在相对较大的系统规模下仍有效。为进一步加速充电，我们优化了脉冲形状并阐明了潜在物理机制。我们的脉冲控制拓扑量子电池协议为实现远程拓扑充电提供了通用框架，并为设计提升量子电池性能的最优控制策略奠定了理论基础。
英文摘要
Quantum batteries have emerged as a promising new generation of energy-storage devices for powering quantum technologies. Long-distance charging is particularly attractive because it minimizes interference between the charger and the battery, thereby attracting considerable interest. Here, we propose a topologically protected long-distance charging protocol for quantum batteries based on a pulse-controlled superconducting qubit chain. By dynamically modulating the pulse-mediated couplings, we realize topologically protected energy transfer from the charger to the battery. We show that the charging process is free of energy backflow and remains robust against imperfections in pulse control. Moreover, the energy stored in the battery at the target time is fully extractable, and the protocol remains effective for relatively large system sizes. To further accelerate charging, we optimize the pulse shape and elucidate the underlying physical mechanism. Our pulse-controlled topological quantum battery protocol provides a versatile framework for implementing long-distance topological charging and establishes a theoretical foundation for designing optimal-control strategies to enhance quantum battery performance.
