Witnessing nonlocality in quantum network of continuous-variable systems by generalized quasiprobability functions

Taotao Yan, Jinchuan Hou, Xiaofei Qi +1

Gaussian measurements can not be used to witness nonlocality in Gaussian states as well as the network nonlocality in networks of continuous-variable (CV) systems. Thus special non…
