论文摘要
在本文中，我们试图解决“张力国家可以具有量子优势吗？”的问题。为了回答这个问题，我们利用了测量引起的非局部性（Min）的概念，并主张基于忠诚度的非局部测量，以捕获由于局部不变的von Neumann投射测量，捕获了延伸状态的非局部效应。我们表明，基于忠诚度的非局部度量的特性是从最小值中检索出来的。从分析上，我们评估了任何任意纯状态的非骨位度量。还根据相关矩阵的特征值获得了基于保真度的非局部度量的上限。作为例证，我们为某些流行的输入状态计算了非局限性。
In the present paper, we attempt to address the question of "can tensorizing states have quantum advantages?". To answer this question, we exploit the notion of measurement-induced nonlocality (MIN) and advocate a fidelity based nonbilocal measure to capture the nonlocal effects of tensorizing states due to locally invariant von Neumann projective measurements. We show that the properties of the fidelity based nonbilocal measure are retrieved from that of MIN. Analytically, we evaluate the nonbilocal measure for any arbitrary pure state. The upper bounds of the nonbilocal measure based on fidelity are also obtained in terms of eigenvalues of correlation matrix. As an illustration, we have computed the nonbilocality for some popular input states.
