摘要:

最近,Chen等人为$2$ -设置和高维系统引入了Hardy悖论的另一种形式[Phy. Rev. A 88,062116(2013)],其中在提高非局部事件的最大概率方面有很大的进展。在这里,我们构造了一个多背景高维系统的广义哈代悖论,它(i)包含了[Phy. Rev. A 88,062116(2013)]作为特例,(ii)对于自旋为1/2的系统,等价于[Phy. Rev. Lett. 13,2755(1997)],(iii)对于自旋为1的系统,通过增加设置的数目来增加非定域事件的最大概率,特别是,仅用5个设置,它就可以提高到0.40184,比Adan悖论中证明非定域性的最大成功概率0.171高出两倍多。Rev. A 58,1687(1998)]。

英文摘要:

Recently, Chen et al introduced an alternative form of Hardy's paradox for $2$-settings and high-dimensional systems [Phy. Rev. A 88, 062116 (2013)], in which there is a great progress in improving the maximum probability of the nonlocal event. Here, we construct a general Hardy's paradox for multi-settings and high-dimensional systems, which (i) includes the paradox in [Phy. Rev. A 88, 062116 (2013)] as a special case, (ii) for spin-1/2 systems, is equivalent to the ladder proof of nonlocality without inequalities in [Phy. Rev. Lett. 13, 2755 (1997)], (iii) for spin-1 systems, increases the maximum probability of the nonlocal event by adding the number of settings, specially, with only 5-settings it can be improved to 0.40184, which is more than two times higher than 0.171, the maximal success probability to prove nonlocality in Adan's paradox [Phy. Rev. A 58, 1687 (1998)].
