论文摘要
通过量子电池的能量存储和传输是量子网络中的关键要素。在这里,我们提出了一个基于无过渡量子驾驶(TQD)的充电器设计,该设计允许对电池充电时间进行固有的控制,充电速度以可用于实施动态的内部能量成本为代价。此外,基于TQD的充电器也被证明是局部稳定的,这意味着在能量传输到QB之后的任何时候,充电器可以与量子电池(QB)断开,而没有完全的能量回流向充电器。这在始终在渐近方案中提供了高电荷的QB。我们说明了QB电荷对时间波动的鲁棒性以及可行的基于TQD充电器的演化时间的完全控制。
The storage and transfer of energy through quantum batteries are key elements in quantum networks. Here, we propose a charger design based on transitionless quantum driving (TQD), which allows for inherent control over the battery charging time, with the speed of charging coming at the cost of the internal energy available to implement the dynamics. Moreover, the TQD-based charger is also shown to be locally stable, which means that the charger can be disconnected from the quantum battery (QB) at any time after the energy transfer to the QB, with no fully energy backflow to the charger. This provides a highly charged QB in an always-on asymptotic regime. We illustrate the robustness of the QB charge against time fluctuations and the full control over the evolution time for a feasible TQD-based charger.
