两种背景下局部真实模型的旋转不变性破坏
Violation of Rotational Invariance of Local Realistic Models with Two Settings
摘要:
我们已经考虑了一个两粒子贝尔实验,以可视化物理定律的旋转不变性和一个特定的本地现实理论之间的冲突。实验是可重复的,通过使用在两个设置贝尔实验中获得的本地现实理论。推广的贝尔不等式{[J. Phys. A:Math. Theor. { \bf 40},13101(2007)]},其是在存在旋转不变的局部现实理论的假设下导出的,证明了用双设置实验来反驳这样的局部现实模型的存在。这意味着这种模型不是旋转不变的,因此在某些情况下应该被排除。
英文摘要:
We have considered a two-particle Bell experiment to visualize the conflict between rotational invariance of physical laws and a specific local realistic theory. The experiment is reproducible by using a local realistic theory obtained in a two-setting Bell experiment. The generalized Bell inequality {[J. Phys. A: Math. Theor. {\bf 40}, 13101 (2007)]}, which is derived under the assumption that there exists a rotationally invariant local realistic theory, turns out to disprove such a local realistic model existing with a two-setting experiment. This implies that such a model is not rotationally invariant and should, therefore, be ruled out in some situations.
