两个自旋半粒子非定域性的阶梯证明

Ladder proof of nonlocality for two spin-half particles revisited

Jose L. Cereceda

摘要:

本文将Boschi等人[PRL 79,2755(1997)]给出的两个自旋半粒子无不等式非定域性的梯形证明推广到测量其中一个粒子的仪器的测量设置不同于测量另一个粒子的仪器的测量设置的情况。它示出,在任何情况下,粒子对的比例,其中的矛盾与当地的现实主义经历时,最大化的测量设置是相同的每个设备。此外,我们写了贝尔不等式的实验问题是违反了量子力学的数量是两倍的量,其中量子力学违反了贝尔不等式考虑在上述文件由Boschi等人。

英文摘要:

In this paper we extend the ladder proof of nonlocality without inequalities for two spin-half particles given by Boschi et al [PRL 79, 2755 (1997)] to the case in which the measurement settings of the apparatus measuring one of the particles are different from the measurement settings of the apparatus measuring the other particle. It is shown that, in any case, the proportion of particle pairs for which the contradiction with local realism goes through is maximized when the measurement settings are the same for each apparatus. Also we write down a Bell inequality for the experiment in question which is violated by quantum mechanics by an amount which is twice as much as the amount by which quantum mechanics violates the Bell inequality considered in the above paper by Boschi et al.
