论文摘要
我们提出了一种新的方法来研究在重置过程中任意开放量子系统的演变。使用更新方程的框架，我们发现了超越单一动力学和马尔可夫测量值的平均第一个返回时间的普遍行为。我们的结果表明，平均切换时间的非平凡行为与平均测量时间$τ$，这允许调整$τ$以最大程度地减少状态之间的平均过渡时间。我们通过数值分析对结果进行补充，并根据unital \ textIt {and}开放系统动力学的低维系统的相应分析研究对结果进行基准测试。
We put forward a novel approach to study the evolution of an arbitrary open quantum system under a resetting process. Using the framework of renewal equations, we find a universal behavior for the mean first return time that goes beyond unitary dynamics and Markovian measurements. Our results show a non-trivial behavior of the mean switching times with the mean measurement time $τ$, which permits tuning $τ$ for minimizing the mean transition time between states. We complement our results with a numerical analysis and we benchmark the results against the corresponding analytical study for low dimensional systems under unitary \textit{and} open system dynamics.
