我们回顾了开放量子系统理论的最新发展，重点是由于系统与环境之间的长期和不可忽略的相关性，水库记忆效应发挥着至关重要的作用。这些系统通常被称为非马尔可夫系统。在简要总结了过去几年中引入的非马尔可夫性的不同度量之后，我们将我们的分析限制在系统与环境之间的信息流的调查上。在这个框架内，我们介绍了一个重要的应用程序的非马尔可夫，即它的使用作为一个量子探针的复杂的量子系统。为了说明这一点，我们考虑量子探针的超冷气体，自旋链，和被困离子晶体，并显示如何提取这些系统的属性可以通过非马尔可夫措施。
We review the most recent developments in the theory of open quantum systems focusing on situations in which the reservoir memory effects, due to long-lasting and non-negligible correlations between system and environment, play a crucial role. These systems are often referred to as non-Markovian systems. After a brief summary of different measures of non-Markovianity that have been introduced over the last few years we restrict our analysis to the investigation of information flow between system and environment. Within this framework we introduce an important application of non-Markovianity, namely its use as a quantum probe of complex quantum systems. To illustrate this point we consider quantum probes of ultracold gases, spin chains, and trapped ion crystals and show how properties of these systems can be extracted by means of non-Markovianity measures.
