论文摘要
贝尔的不平等可能会通过对铃铛州的测量结果进行选择来违反。如果有有关原始状态准备的信息，我们指出如何通过根据此信息进行后选择来经典地重现违规行为。因此，我们提出了一种现有实验的一种变体，这些变体通过在距离分离时进行准备和选择后排除这种替代解释。与临时情况不同，基于钟形状态前或选择后，人们可以彻底区分贝尔不平等的行为，在我们的情况下，这些物理效应之间的区别依赖于叶面。我们称此为“前和选择后的相对论”。
The Bell inequalities can be violated by postselecting on the results of a measurement of the Bell states. If information about the original state preparation is available, we point out how the violation can be reproduced classically by postselecting on the basis of this information. We thus propose a variant of existing experiments that rules out such alternative explanations, by having the preparation and the postselection at spacelike separation. Unlike the timelike case where one can sharply distinguish Bell inequality violations based on pre- or postselection of a Bell state, in our scenario the distinction between these physical effects becomes foliation-dependent. We call this 'relativity of pre- and postselection'.
