The performance of quantum technologies that use entanglement and coherence as resource is highly limited by decohering effects due to their interaction with some environment. Particularly, it is important to take into account situations where such devices unavoidably interact with a surrounding. Here, we study memory effects on energy and ergotropy of quantum batteries in the framework of open system dynamics, where the battery and charger are individually allowed to access a bosonic environment. Our investigation shows that the battery can be fully charged and its energy can be preserved for long times in non-Markovian dynamics compared with Markovian dynamics. In addition, the total stored energy can be completely extracted as work and discharge time becomes more longer as non-Markovianity increases. Our results indicate that memory effects can play a significant role in improving the performance of quantum batteries.

量子电池充放电过程的非马尔可夫效应

使用纠缠和相干作为资源的量子技术的性能由于与某些环境的相互作用而受到退相干效应的高度限制。特别是，考虑此类设备不可避免地与周围环境交互的情况非常重要。在这里，我们在开放系统动力学的框架内研究了量子电池对能量和运动性的记忆效应，其中电池和充电器被单独允许进入玻色子环境。我们的调查表明，与马尔可夫动力学相比，在非马尔可夫动力学中，电池可以充满电并且其能量可以长时间保存。此外，随着非马尔可夫性的增加，工作和放电时间变得更长，可以完全提取总存储能量。
