摘要:

在极化实验中证实了自旋-能量纠缠中子态的类Bell不等式的破坏。在Clauser-Horne-Shimony-Holt(CHSH)形式主义中,所提出的不等式依赖于单中子系统中自旋和能量自由度之间的相关性。利用两个射频场的适当组合在中子偏振仪设置产生的纠缠态。关联函数S被确定为2.333+/-0.005,其违反Bell类CHSH不等式超过66个标准差。

英文摘要:

Violation of a Bell-like inequality for a spin-energy entangled neutron state has been confirmed in a polarimetric experiment. The proposed inequality, in Clauser-Horne-Shimony-Holt (CHSH) formalism, relies on correlations between the spin and energy degree of freedom in a single-neutron system. The entangled states are generated utilizing a suitable combination of two radio-frequency fields in a neutron polarimeter setup. The correlation function S is determined to be 2.333+/-0.005, which violates the Bell-like CHSH inequality by more than 66 standard deviations.
