论文摘要

我们定义了一种基于行为的贝尔非局部性量化状态非局部性的替代方法,称为痕量加权非局部体积。该结构基于非局部体积,这是一个非局部性的量词,该状态的量化量是计算应用到该状态时会导致非本地行为的一组测量值的数量,以及基于行为距离和局部集合之间的距离的非局部距离的痕量距离。先前候选人的关键区别在于引入非局部性的量词来加重非本地体积行为的每个贡献。我们列出了此量词的一些有趣属性,并研究(2、2、2)和(2、3、2)方案。我们表明,(2、2、3)场景的非局部性的弱异常持续存在,但是与非加权版本的最小值相比,与痕量加权非内部的非本地性最低限度发生在不同的状态下,表明弱的异常是该场景的interinsic interincors of Ventents的特征,而是选择了量子的依赖性。

We define an alternative way of quantifying nonlocality of states based on Bell nonlocality of behaviors, called the trace-weighted nonlocal volume. The construction is based on the nonlocal volume, a quantifier of nonlocality for states that counts the volume of the set of measurements that give rise to nonlocal behaviors when applied to this state, plus the trace distance, a quantifier of nonlocality for behaviors based on the distance between the behavior and the local set. The key difference from preceding candidates was the introduction of a quantifier of nonlocality to weight each contribution from behaviors in the nonlocal volume. We list some interesting properties of this quantifier and investigate the (2, 2, 2) and (2, 3, 2) scenarios. We show that the weak anomaly of nonlocality for the (2, 2, 3) scenario persists, but the local minimum for nonlocality with the trace-weighted nonlocal volume occurs in a different state as compared to the minimum for the non-weighted version, showing that the weak anomaly is not an intrinsic characteristic of the scenario, but is dependent of the choice of quantifier.
