三缝实验与量子非定域性

Three-slit experiments and quantum nonlocality

Gerd Niestegge

摘要:

揭示了量子力学两个非常不同的物理方面之间的一个有趣的联系;这两个方面是三阶干涉的不存在和Tsirelson的非局域相关性。考虑到多缝实验--不仅是传统的两缝结构,还有三缝或更多缝的结构--索尔金发现,在量子力学中,三阶(和更高阶)干涉是不可能的。EPR实验表明,量子力学包含非定域关联,这些关联违反了Bell或CHSH不等式,但仍然受到Tsirelson发现的一个界限的限制。现在证明,只要排除了三阶干扰,Tsirelson的界限在广泛的概率理论中成立。这一类的一个主要特点是存在一个合理的条件概率演算,或者用更物理的说法,存在一个合理的量子测量过程模型。

英文摘要:

An interesting link between two very different physical aspects of quantum mechanics is revealed; these are the absence of third-order interference and Tsirelson's bound for the nonlocal correlations. Considering multiple-slit experiments - not only the traditional configuration with two slits, but also configurations with three and more slits - Sorkin detected that third-order (and higher-order) interference is not possible in quantum mechanics. The EPR experiments show that quantum mechanics involves nonlocal correlations which are demonstrated in a violation of the Bell or CHSH inequality, but are still limited by a bound discovered by Tsirelson. It now turns out that Tsirelson's bound holds in a broad class of probabilistic theories provided that they rule out third-order interference. A major characteristic of this class is the existence of a reasonable calculus of conditional probability or, phrased more physically, of a reasonable model for the quantum measurement process.
