Enhancement of three-mode Gaussian state light field nonlocality
三模高斯态光场非局域性的增强

Here we propose a scheme for enhancing the nonlocality of three-mode Gaussian state light fields. It is found that three-mode Gaussian State can become non-Gaussian by the non-Gaussian operation of an IPS process, It is vertified that nonlocality of Gaussian state can be enhanced by Bell inquality.
