论文摘要
我们对由许多相同的量子电池组成的量子电池的能量回收效率进行了理论分析。尽管已经大量研究了使用量子效应来加快电池充电过程的可能性，但为了将这些想法塑造到工作设备中，在与环境噪声接触时评估存储阶段在量子电池元素中的稳定性至关重要。在这项工作中，我们将此问题形式化，引入了一系列运营良好的功绩（工作电容和最大渐近工作/能量比率），这些图表衡量了人们可以从相同和独立元素或独立元素（量子或Q-Cells）中恢复有用的量子电池模型中最高效率。对于能量存储系统通过去极化和去极化噪声进行的情况，对这种数量进行了明确的评估。
We present a theoretical analysis of the energy recovery efficiency for quantum batteries composed of many identical quantum cells undergoing noise. While the possibility of using quantum effects to speed up the charging processes of batteries have been vastly investigated, In order to traslate these ideas into working devices it is crucial to assess the stability of the storage phase in the quantum battery elements when they are in contact with environmental noise. In this work we formalize this problem introducing a series of operationally well defined figures of merit (the work capacitances and the Maximal Asymptotic Work/Energy Ratios) which gauge the highest efficiency one can attain in recovering useful energy from quantum battery models that are formed by large collections of identical and independent elements (quantum cells or q-cells). Explicit evaluations of such quantities are presented for the case where the energy storing system undergoes through dephasing and depolarizing noise.
