我们介绍了一种开放的量子电池协议，使用暗态来获得超大容量和功率密度，并将非相互作用的自旋耦合到库中。此外，我们的功率密度实际上随着电池中自旋的数量而增加。我们证明了增强的容量和功率与纠缠是相关的。当连接到充电器时，电池的充电状态是稳定的状态，通过开放系统中的量子干涉稳定下来。
We introduce an open quantum-battery protocol using dark states to achieve both superextensive capacity and power density, with noninteracting spins coupled to a reservoir. Further, our power density actually scales with the number of spinsin the battery. We show that the enhanced capacity and power are correlated with entanglement. While connected to the charger, the charged state of the battery is a steady state, stabilized through quantum interference in the open system.
