论文摘要
在过去的几年中,机器学习方法的应用在不同的物理领域变得越来越重要。开放量子系统理论中最重要的主题之一是研究非马克维亚记忆效应的表征,在开放系统与周围环境相互作用时,它们在整个开放系统的演变过程中会动态出现。在这里,我们考虑了两个公认的记忆效应程度的量词,即痕量距离和基于纠缠的非马克维亚性测量。我们证明,使用机器学习技术,尤其是支持向量机算法,可以在两个具有高精度的范式开放系统模型中估算非摩托车的程度。我们的方法在实验上可以是可行的,以估计非马克维亚性的程度,因为它需要单一或最多两轮状态断层扫描。
In the last years, the application of machine learning methods has become increasingly relevant in different fields of physics. One of the most significant subjects in the theory of open quantum systems is the study of the characterization of non-Markovian memory effects that emerge dynamically throughout the time evolution of open systems as they interact with their surrounding environment. Here we consider two well-established quantifiers of the degree of memory effects, namely, the trace distance and the entanglement-based measures of non-Markovianity. We demonstrate that using machine learning techniques, in particular, support vector machine algorithms, it is possible to estimate the degree of non-Markovianity in two paradigmatic open system models with high precision. Our approach can be experimentally feasible to estimate the degree of non-Markovianity, since it requires a single or at most two rounds of state tomography.
