论文摘要
量子非局部性的众所周知的特性是一夫一妻制的。但是,Silva \ emph {等人}的最新研究表明,多个观察者可以使用弱测量结果共享非局部性[物理。莱特牧师。 114,250401(2015)]。他们的结果剩下一个空旷的问题:是否可以在两个以上的观察者中共享一个纠缠对的单个粒子的非局部性,这些观察者彼此依次和独立地行事?在这项工作中,我们的分析和数值表明,当相对于先前的观察者而言,一侧几个观察者的测量值都没有偏见,可以观察到爱丽丝和三个鲍勃之间的CHSH不平等的三重违规。该结果推翻了以前在科学界广泛共享此问题的相关工作的结论和证据。
A well-known property of quantum nonlocality is monogamy. However, recent research by Silva \emph{et al.} shows that multiple observers can share the nonlocality by using weak measurements [Phys. Rev. Lett. 114, 250401 (2015)]. There is an open question left in their result: whether the nonlocality of a single particle from an entangled pair can be shared among more than two observers that act sequentially and independently of each other? In this work, we analytical and numerical shows that it is possible to observe a triple violation of CHSH inequality between Alice and three Bobs when the measurements of each of the several observers at one side are unbiased with respect to the previous observers. This result overturns the conclusions and proofs of previous related work on this issue which has been widely shared in the scientific community before.
