论文摘要
热力学熵产生与非马克维亚进化之间的关系是当前研究的问题。在这里，我们研究了正在进行Unital non-Markovian动力学的开放量子系统中随机熵产生的行为。特别是，对于保利通道的家族，我们表明，在某些特定的时间间隔中，平均熵产生和方差都可以降低，前提是量子动力学不可分割。尽管系统的动力学总体不可逆，但我们的结果可能被解释为具有可逆性的短暂趋势，被描述为零熵产生的峰值分布。最后，我们还提供了产生量子系统动力学的发电机中参数的分析界限，以确保缓解相应的非马克维亚进化的不可逆性。
The relation between the thermodynamic entropy production and non-Markovian evolutions is matter of current research. Here, we study the behavior of the stochastic entropy production in open quantum systems undergoing unital non-Markovian dynamics. In particular, for the family of Pauli channels we show that in some specific time intervals both the average entropy production and the variance can decrease, provided that the quantum dynamics fails to be P-divisible. Although the dynamics of the system is overall irreversible, our result may be interpreted as a transient tendency towards reversibility, described as a delta peaked distribution of entropy production around zero. Finally, we also provide analytical bounds on the parameters in the generator giving rise to the quantum system dynamics, so as to ensure irreversibility mitigation of the corresponding non-Markovian evolution.
