Separability of rank two quantum states on multiple quantum spaces with
different dimensions
Shao-Ming Fei, Xiu-Hong Gao, Xiao-Hong Wang, Zhi-Xi Wang, Ke Wu
abstract: 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 multiparty quantum states are explicitly presented. A
nonseparability inequality is also given, for the case where one of the
eigenvectors corresponding to nonzero eigenvalues of the density matrix is
maximally entangled.
