论文摘要
在本文中，我们提出了使用von Neumann射击测量测量的测量诱导的非局部性（min）。提出的最小是非局部相关性的真正度量，并且对局部附属问题有抵抗力。我们获得了一般纯净的Hellinger距离最小值的分析表达和2美元的混合状态。除了与类似措施进行比较外，我们还探讨了弱测量在捕获非局部相关性中的作用。
In this article, we propose measurement-induced nonlocality (MIN) quantified by Hellinger distance using von Neumann projective measurement. The proposed MIN is a bonafide measure of nonlocal correlation and is resistant to local ancilla problem. We obtain an analytical expression of the Hellinger distance MIN for general pure and $2 \otimes n$ mixed states. In addition to comparing with similar measures, we explore the role of weak measurement in capturing nonlocal correlation.
