分析了d能级量子系统随机幺正演化的非马尔可夫性程度。它示出了如何在本地退相干率的非马尔可夫度的特点。特别是，我们推导出一个充分条件消失的回流的信息和这个概念的其他特点的非马尔可夫。
We analyze the non-Markovianity degree for random unitary evolution of d-level quantum systems. It is shown how the non-Markovianity degree is characterized in terms of local decoherence rates. In particular we derive a sufficient condition for vanishing of the backflow of information and relate this concept to other characteristics of non-Markovianity.
