摘要:

我们考虑了具有相位奇异性的光束,并从实验上证实了这些光束虽然是经典的,但在量子态中具有双模纠缠的性质。我们已经使用Chowdhury等人提出的Wigner分布函数(WDF)观察到连续变量的Bell不等式的违反[Phys. Rev. A \textbf{88},013830(2013)]。我们的实验建立了一种新形式的贝尔不等式的WDF,可用于经典以及量子系统。

英文摘要:

We have considered optical beams with phase singularity and experimentally verified that these beams, although being classical, have properties of two mode entanglement in quantum states. We have observed the violation of Bell's inequality for continuous variables using the Wigner distribution function (WDF) proposed by Chowdhury et al. [Phys. Rev. A \textbf{88}, 013830 (2013)]. Our experiment establishes a new form of Bell's inequality in terms of the WDF which can be used for classical as well as quantum systems.
