论文摘要
量子记忆效应可以是由于环境到系统回流的结果而定性地理解的。在这里，我们分析并比较了如何以不同的量子非马克维亚性方法来解释和实施该概念。我们研究了一种非运营方法，该方法由两个以不同初始条件为特征的系统状态与操作方法之间定义，该方法是由与感兴趣系统执行的连续测量过程相关的不同结果之间的相关性所定义的。每种方法的差异，局限性和范围都通过考虑各种系统环境模型和动态来详细介绍。作为一个具体的例子，我们研究了一个非马克维亚去极化图，该图引起的感兴趣系统与以不连贯和连贯的自我动力学为特征的环境相互作用。
Quantum memory effects can be qualitatively understood as a consequence of an environment-to-system backflow of information. Here, we analyze and compare how this concept is interpreted and implemented in different approaches to quantum non-Markovianity. We study a non-operational approach, defined by the istinguishability between two system states characterized by different initial conditions, and an operational approach, which is defined by the correlation between different outcomes associated to successive measurement processes performed over the system of interest. The differences, limitations, and vantages of each approach are characterized in detail by considering diverse system-environment models and dynamics. As a specific example, we study a non-Markovian depolarizing map induced by the interaction of the system of interest with an environment characterized by incoherent and coherent self-dynamics.
