论文摘要
我们研究量子资源与量子电池中可提取的工作之间的联系。我们证明，电池或电池符号纠缠中的量子相干性是在充电过程中生成非零可提取工作的必要资源。在充电过程结束时，我们还建立了与最终可提取工作的连贯性和纠缠的紧密联系：连贯性自然促进了连贯的工作，同时连贯和纠缠抑制了不连贯的工作。我们还表明，获得最大相干的工作要比获得最大不连贯的工作要快。给出了从中央自旋电池和塔维斯 - 塞电池到旋转链电池的示例，以说明这些结果。
We investigate the connection between quantum resources and extractable work in quantum batteries. We demonstrate that quantum coherence in the battery or the battery-charger entanglement is a necessary resource for generating nonzero extractable work during the charging process. At the end of the charging process, we also establish a tight link of coherence and entanglement with the final extractable work: coherence naturally promotes the coherent work while coherence and entanglement inhibit the incoherent work. We also show that obtaining maximally coherent work is faster than obtaining maximally incoherent work. Examples ranging from the central-spin battery and the Tavis-Cummings battery to the spin-chain battery are given to illustrate these results.
