Separability of rank two quantum states on multiple quantum spaces with different dimensions
Shao-Ming Fei, Xiu-Hong Gao, Xiao-Hong Wang +2
We consider the separability of rank two quantum states on multiple quantum spaces with different dimensions. The sufficient and necessary conditions for separability of these mult…
