关于非马尔可夫性的度量:可分性与信息回流

On measures of non-Markovianity: divisibility vs. backflow of information

Dariusz Chruściński, Andrzej Kossakowski, Ángel Rivas

摘要:

我们分析了最近提出的两种非马尔可夫性测度:一种是基于动力学映射的可分性概念,另一种是基于量子态的可分性概念。我们提供了一个玩具模型来表明,这两个措施不需要同意。此外,我们还讨论了这些措施之间可能的推广和错综复杂的关系。

英文摘要:

We analyze two recently proposed measures of non-Markovianity: one based on the concept of divisibility of the dynamical map and the other one based on distinguishability of quantum states. We provide a toy model to show that these two measures need not agree. In addition, we discuss possible generalizations and intricate relations between these measures.
