关于敌手的内禀不对称性:贝尔不等式的新特征
Intrinsic asymmetry with respect to adversary: new feature of Bell inequalities
摘要:
已知贝尔不等式的局部界对外部观测者关于设置统计的知识是敏感的。在这里,我们要问的是,这种敏感性如何取决于这种知识的结构。事实证明,在某些情况下,它可能会发生的本地边界是更敏感的对手的知识,一方的设置比其他。值得注意的是,有贝尔不等式这是高度不对称的对手的知识,当地的设置。这个性质可以看作是贝尔不等式的一个隐藏的内在不对称性。揭示的不对称效应的潜在影响进行了讨论。
英文摘要:
It is known that the local bound of a Bell inequality is sensitive to the knowledge of the external observer about the settings statistics. Here we ask how that sensitivity depends on the structure of that knowledge. It turns out that in some cases it may happen that the local bound is much more sensitive to adversary's knowledge about settings of one party than the other. Remarkably, there are Bell inequalities which are highly asymmetric with respect to the adversary's knowledge about local settings. This property may be viewed as a hidden intrinsic asymmetry of Bell inequalities. Potential implications of the revealed asymmetry effect are also discussed.
