In this study, we have proposed a method based on non-equilibrium effects to generate the superposition of macroscopically distinguishable quantum states, known as Schrodinger cat states, by using a Mach-Zehnder interferometry type experiment. Interaction of the input number state with a Kerr medium in the presence of a couple of heat baths in different temperatures in interaction picture and without imposing Markov assumption is considered. We have shown that the study of dynamics of the cat states under non-equilibrium condition open a way for the robustness of quantum features against the destructive role of the environment even at high temperature limit. It is verified that mutual influence of the environments, far from equilibrium, on the open system, makes it possible to revive quantum beats for longer time intervals. Moreover, we have probed how the traits of the environment, like its temperature and the Ohmic, super-Ohmic or sub-Ohmic functionality of the spectral density, may affect the pattern of the oscillation between alive or dead states of the cat.

通过非平衡呼吸使薛定谔的猫栩栩如生

在这项研究中，我们提出了一种基于非平衡效应的方法，通过使用 Mach-Zehnder 干涉测量类型实验来生成宏观可区分的量子态（称为薛定谔猫态）的叠加。考虑了输入数态与克尔介质的相互作用，在交互图中存在几个不同温度的热浴，并且不强加马尔可夫假设。我们已经表明，对非平衡条件下猫态动力学的研究为量子特征的鲁棒性开辟了道路，即使在高温极限下也能抵抗环境的破坏性作用。经证实，远离平衡的环境对开放系统的相互影响使得在更长的时间间隔内恢复量子节拍成为可能。而且，
