PR盒相关性没有经典极限

PR-box correlations have no classical limit

Daniel Rohrlich

摘要:

亚基尔·阿哈罗诺夫(Yakir Aharonov)的一个令人着迷的物理学观点是,他猜想两个公理,即相对论因果关系(“没有超光速信号”)和非定域性,几乎相互矛盾,以至于一个独特的理论--量子力学--调和了它们。但超量子(或“PR盒”)关联意味着量子力学不是与相对论因果性最一致的非定域理论(在非定域关联的意义上)。让我们考虑用最小的第三个公理来补充这两个公理:存在一个经典极限,在这个极限中宏观可观测量可交换。也就是说,就像量子力学有一个经典极限一样,任何量子力学的推广也必须有一个经典极限。在这个经典极限中,PR盒关联违反了相对论因果关系。推广到所有强于量子的二分关联,这个结果是一个推导Tsirelson的界限,而不假设量子力学。

英文摘要:

One of Yakir Aharonov's endlessly captivating physics ideas is the conjecture that two axioms, namely relativistic causality ("no superluminal signalling") and nonlocality, so nearly contradict each other that a unique theory - quantum mechanics - reconciles them. But superquantum (or "PR-box") correlations imply that quantum mechanics is not the most nonlocal theory (in the sense of nonlocal correlations) consistent with relativistic causality. Let us consider supplementing these two axioms with a minimal third axiom: there exists a classical limit in which macroscopic observables commute. That is, just as quantum mechanics has a classical limit, so must any generalization of quantum mechanics. In this classical limit, PR-box correlations violate relativistic causality. Generalized to all stronger-than-quantum bipartite correlations, this result is a derivation of Tsirelson's bound without assuming quantum mechanics.
