地方实在论、语境论与贝尔实验的漏洞

Local Realism, Contextualism and Loopholes in Bell`s Experiments

Andrei Khrennikov, Igor Volovich

摘要:

由于Bell定理和相关实验的结果,目前人们普遍认为量子力学与定域实在论不一致,存在所谓的量子非定域性。我们证明,只有在忽略空间和时间存在这一基本事实的情况下,这种主张才能在量子力学的简化方法中得到证明。给出了Bell意义下和Einstein意义下局域实在论的数学定义。我们证明,如果我们纳入到量子力学的形式主义的时空结构在标准的方式,然后量子力学可能是符合爱因斯坦的局域现实主义。它表明,漏洞是不可避免的,旨在建立一个违反贝尔不等式的实验。我们展示了如何时空结构可以被认为是从上下文的角度来看。一个数学框架的上下文方法概述。

英文摘要:

It is currently widely accepted, as a result of Bell's theorem and related experiments, that quantum mechanics is inconsistent with local realism and there is the so called quantum non-locality. We show that such a claim can be justified only in a simplified approach to quantum mechanics when one neglects the fundamental fact that there exist space and time. Mathematical definitions of local realism in the sense of Bell and in the sense of Einstein are given. We demonstrate that if we include into the quantum mechanical formalism the space-time structure in the standard way then quantum mechanics might be consistent with Einstein's local realism. It shows that loopholes are unavoidable in experiments aimed to establish a violation of Bell`s inequalities. We show how the space-time structure can be considered from the contextual point of view. A mathematical framework for the contextual approach is outlined.
