EPR悖论、贝尔不等式和定域性问题

The EPR paradox, Bell's inequality, and the question of locality

Guy Blaylock

摘要:

大多数物理学家都同意爱因斯坦-波多尔斯基-罗森-贝尔悖论解释了量子力学的许多奇怪行为,但关于悖论背后的假设仍然存在争议。为了澄清这场争论的内容,我们采用了一个简单而著名的思想实验,这个实验涉及两个相关的光子,以帮助我们把注意力集中在构建EPR和贝尔论证所需的逻辑假设上。本文提出的观点是,贝尔不等式背后的最小假设是局部性和反事实的确定性,而不是科学实在论,决定论,或隐藏的变量,因为经常建议。我们进一步研究由此产生的限制物理理论的说明从多世界的解释量子力学-一种解释,我们认为是确定性的,本地的,现实主义的,但仍然违反了贝尔不等式。

英文摘要:

Most physicists agree that the Einstein-Podolsky-Rosen-Bell paradox exemplifies much of the strange behavior of quantum mechanics, but argument persists about what assumptions underlie the paradox. To clarify what the debate is about, we employ a simple and well-known thought experiment involving two correlated photons to help us focus on the logical assumptions needed to construct the EPR and Bell arguments. The view presented in this paper is that the minimal assumptions behind Bell's inequality are locality and counterfactual definiteness, but not scientific realism, determinism, or hidden variables, as is often suggested. We further examine the resulting constraints on physical theory with an illustration from the many-worlds interpretation of quantum mechanics -- an interpretation that we argue is deterministic, local, and realist, but that nonetheless violates the Bell inequality.
