系统环境相关性决定了动态过程的(非)马尔可夫特征,是开放量子系统研究中一个非常有趣的领域。我们将量子点样品发射的光子送入15米保偏光纤中,产生不同的系统环境相关态,然后通过观察示踪距离的增长来见证相关性。该基于系统环境信息流的关联见证实验方案也可用于其他类似系统。
System-environment correlations, which determine the (non-)Markovian character of a dynamical process, is an area of intense interest in the study of open quantum systems. We send photons emitted from a quantum dot sample into a 15-m polarization-maintaining optical fiber to generate different system-environment correlated states and then witness the correlations by observing the growth of trace distances. This experimental scheme of correlation witnessing based on system-environment information flow can also be used for other similar systems.
