The CHSH-type inequalities for infinite-dimensional quantum systems
Yu Guo
By establishing CHSH operators and CHSH-type inequalities, we show that any entangled pure state in infinite-dimensional systems is entangled in a subspace. We find tha…

A generalization of Schmidt number for multipartite states
Yu Guo, Heng Fan
The Schmidt number is of crucial importance in characterizing the bipartite pure states. We explore and propose here a generalization of Schmidt number for states in multipartite s…
