论文摘要
我们表明,非马克维亚开放量子系统可以表现出最长时间的马尔可夫动力学。因此,此类系统的非马克维亚性是完美的“隐藏”,即仅通过查看减少的动力学而无法在实验上检测到。这表明非马克维亚性在物理上是不可证明的,并且极其违反直觉,因为它的特征可以随时而没有前体。讨论了一些有趣的例子。
We show that non-Markovian open quantum systems can exhibit exact Markovian dynamics up to an arbitrarily long time; the non-Markovianity of such systems is thus perfectly "hidden", i.e. not experimentally detectable by looking at the reduced dynamics alone. This shows that non-Markovianity is physically undecidable and extremely counterintuitive, since its features can change at any time, without precursors. Some interesting examples are discussed.
