论文摘要
提出了测量引起的非局部性（min），以测量由局部不变的测量引起的最大全局效应。类似地，测量引起的非局部相关性是最小的概括，可用于测量双腹场景中局部测量引起的最大全球影响。在本文中，我们根据Wigner-Yanase偏斜信息提出了一种新的非局部相关度量。讨论了基于Wigner-Yanase偏斜信息的最小值与我们的度量之间的关系。我们提出了对纯输入状态的度量的分析表达，并为输入一般混合状态提供了上限。
Measurement-induced nonlocality (MIN) was proposed for measure the maximum global effect caused by locally invariant measurements. Similarly, the Measurement-induced nonbilocal correlation is a generalization of MIN can be used to measure the maximal global influence caused by the local measurement in the bilocal scenario. In this paper, we propose a new nonbilocal correlation measure based on the Wigner-Yanase skew information. The relationship between the MIN based on Wigner-Yanase skew information and our measure is discussed. We present an analytical expression of our measure for pure input states and also provide upper bounds for input general mixed states.
