信息因果性原理对Hardy非定域性的约束

量子物理 2013-01-17 v2

摘要

最近,不违反信息因果性的原理 [Nature 461, 1101 (2009)] 被提出作为自然界的基本属性之一。我们在受信息因果性不违反原理限制的广义概率论框架下,探讨了两量子比特系统的Hardy非定域性定理。应用信息因果性违反的一个充分条件,我们推导出了Hardy非定域性论证的最大成功概率的上界。我们发现,这里得到的上界高于量子力学所允许的值,但仍远低于无信号条件所允许的值。我们还在此背景下研究了Cabello型非定域性论证(Hardy论证的推广)。

Abstract modified, changes made in the conclusion, throughout the paper we clarified that the condition used by us is protocal based and is only a sufficient condition for the violation of information causality
