Separability of rank two quantum states on multiple quantum spaces with different dimensions

Quantum Physics 2007-05-23 v1

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.
