我们根据动态图的光谱特性对非马尔可夫量子演化进行分析。我们引入了纠缠见证的动态模拟来检测非马尔可夫性，并用几个有启发性的例子来说明其行为。结果表明，对于几个重要的动态映射类别，映射的奇异值和/或特征值的相应演化提供了简单的非马尔可夫性见证。
We provide an analysis on non-Markovian quantum evolution based on the spectral properties of dynamical maps. We introduce the dynamical analog of entanglement witness to detect non-Markovianity and we illustrate its behavior with several instructive examples. It is shown that for several important classes of dynamical maps the corresponding evolution of singular values and/or eigenvalues of the map provides a simple non-Markovianity witness.
