论文摘要
非局部性是量子理论的独特特征，量子理论已被广泛研究了数十年。发现不确定性原理决定了量子力学的非局部性。在这里，我们表明相关系统中各种非定位程度的特征是普遍的不确定性原理，互补性归因于可观察到的相互依赖性。提供了与不同依赖顺序有关的不同类型的非古典现象的具体例子。我们获得了第三阶``陷入非局部性''，发现钟的非局部性仅仅是第二阶``差异''''''差异''，而第四顺序依赖性包含换向器正方形，因此，这与量子上下文相关。预计普遍的不确定性原则的更多应用。
Nonlocality is a distinctive feature of quantum theory, which has been extensively studied for decades. It is found that the uncertainty principle determines the nonlocality of quantum mechanics. Here we show that various degrees of nonlocalities in correlated system can be characterized by the generalized uncertainty principle, by which the complementarity is attributed to the mutual dependence of observables. Concrete examples for different kinds of non-classical phenomena pertaining to different orders of dependence are presented. We obtain the third order ``skewness nonlocality'', and find that the Bell nonlocality turns out to be merely the second order ``variance nonlocality'' and the forth order dependence contains the commutator squares, which hence is related to the quantum contextuality. More applications of the generalized uncertainty principle are expected.
