Nonclassicality Non-Gaussianity Phase Space
2016/1/22
We theoretically propose and experimentally demonstrate a nonclassicality test of a single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banaszek and Wódkiewicz...
A signal-strength model for gravity-field spectrum components in a local space
