拟用实验检验量子关联的界限

Proposed experiment to test the bounds of quantum correlations

Adan Cabello

摘要:

Clauser-Horne-Shimony-Holt不等式可以给出经典界2和Tsirelson界2之间的值\sqrt 2。然而,对于给定的一组局部可观测量,在这个范围内存在任何量子态都无法达到的值。我们提供的解析表达式为相应的约束的参数化的本地观测量引入Filipp和Svozil,并描述了如何实验跟踪它使用的单态源。这样的实验将有助于确定贝尔不等式实验中实验误差的来源,并且可以修改以检测超出量子力学预测的假设相关性。

英文摘要:

Clauser-Horne-Shimony-Holt inequality can give values between the classical bound, 2, and Tsirelson's bound, 2 \sqrt 2. However, for a given set of local observables, there are values in this range which no quantum state can attain. We provide the analytical expression for the corresponding bound for a parametrization of the local observables introduced by Filipp and Svozil, and describe how to experimentally trace it using a source of singlet states. Such an experiment will be useful to identify the origin of the experimental errors in Bell's inequality-type experiments and could be modified to detect hypothetical correlations beyond those predicted by quantum mechanics.
