论文摘要
利用测量引起的非局部性的概念[Phys.Rev。 Lett。 106，120401（2011）]，我们引入了一种量化非局部相关性的新措施。我们在任意纯输入状态的非局部和非局部度量之间建立了一个简单的关系。考虑到混合状态为输入，我们得出了基于亲和力的非局部度量的两个上限。最后，我们研究了输入状态不同组合的非漏洞性。
Exploiting the notion of measurement-induced nonlocality [Phys.Rev. Lett. 106, 120401 (2011)], we introduce a new measure to quantify the nonbilocal correlation. We establish a simple relation between the nonlocal and nonbilocal measures for the arbitrary pure input states. Considering the mixed states as inputs, we derive two upper bounds of affinity-based nonbilocal measure. Finally, we have studied the nonbilocality of a different combinations of input states.
