碰撞模型中耗散引起的信息置乱
Dissipation induced information scrambling in a collision model
摘要：
在本文中，我们提出了一个碰撞模型，频闪模拟耗散系统中的信息动力学。特别地，提出了一种全光方案来研究具有高斯环境态的玻色子系统的信息置乱。通过改变环境的状态，我们发现，在耗散的存在下，系统模式的瞬态三方互信息可能会显示为负值，信号的信息置乱的出现。我们还发现，基于动态不可分性的非马尔可夫性在影响信息的动态性方面起着双重作用。
英文摘要：
In this paper, we present a collision model to stroboscopically simulate the dynamics of information in dissipative systems. In particular, an all-optical scheme is proposed to investigate the information scrambling of bosonic systems with Gaussian environmental states. By varying the states of environments, we find that in the presence of dissipation the transient tripartite mutual information of system modes may show negative value signaling the appearance of information scrambling. We also find that dynamical indivisibility based non-Markovianity play dual roles in affecting the dynamics of information.
