论文摘要
使用量子优势在量子系统的自由度中存储能量的设备由于其作为量子电池的特性而引起了人们的注意。但是，人们可以在这些设备的实际制造过程之前确定需要充分解决的许多问题。特别是，重要的是要注意量子电池在没有连接的消耗中心时量子电池在存储能源中的能力。在本文中，通过考虑与外部充电场和消耗中心断开连接的量子电池，我们研究了导致泄漏到周围环境的疏离效应。我们将这种现象识别为QB的自我递减，类似于开路配置中常规经典电池的固有衰减。对于单细胞量子电池，突出显示了有关经典对应物的量子优势。
Devices that use quantum advantages for storing energy in the degree of freedom of quantum systems have drawn attention due to their properties of working as quantum batteries. However, one can identify a number of problems that need to be adequately solved before a real manufacturing process of these devices. In particular, it is important paying attention to the ability of quantum batteries in storing energy when no consumption center is connected to them. In this paper, by considering quantum batteries disconnected from external charging fields and consumption center, we study the decoherence effects that lead to charge leakage to the surrounding environment. We identify this phenomena as a self-discharging of QBs, in analogy to the inherent decay of the stored charge of conventional classical batteries in a open-circuit configuration. The quantum advantage concerning the classical counterpart is highlighted for single- and multi-cell quantum batteries.
