论文摘要
非马克维亚人时有一定的动态，绝不会展示信息回流。我们表明，如果在这两个动态映射的应用顺序不确定的情况下考虑了两个这样的动态图，则有效的通道可以表现出信息回流。特别是，我们使用量子开关激活这种通道。相反，即使在串联或并行作用中使用许多此类通道的副本，也无法激活这些通道。然后，我们研究了量子开关实验背后的动力学，并发现在量子开关的作用后，CP（完全为正） - 可除外性和P（正） - 通道的可分解率分解，以及信息回流的激活。我们的研究通过研究其动力学行为来阐明量子开关的优势。
There are certain dynamics while being non-Markovian, do never exhibit information backflow. We show that if two such dynamical maps are considered in a scenario where the order of application of these two dynamical maps are not definite, the effective channel can manifest information backflow. In particular, we use quantum SWITCH to activate such a channel. In contrast, activation of those channels are not possible even if one uses many copies of such channels in series or in parallel action. We then investigate the dynamics behind the quantum SWITCH experiment and find out that after the action of quantum SWITCH both the CP (Complete Positive)- divisibility and P (Positive)- divisibility of the channel breaks down, along with the activation of information backflow. Our study elucidate the advantage of quantum SWITCH by investigating its dynamical behavior.
