摘要:

在连续时间开放量子系统动力学的背景下,分析了噪声系统与辅助系统之间纠缠的时间演化。针对量子比特系统的几个解析可解模型,我们研究了马尔可夫和非马尔可夫特性如何影响问题,特别讨论了它们相关的纠缠破坏机制。这些性能相比,当系统的环境是被迫返回到其输入配置通过定期瞬时复位程序可以实现。

英文摘要:

The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a couple of analytically solvable models for qubit systems, we study how Markovian and non-Markovian characteristics influence the problem, discussing in particular their associated entanglement-breaking regimes. These performances are compared with those one could achieve when the environment of the system is forced to return to its input configuration via periodic instantaneous resetting procedures.
