Separability criteria based on Heisenberg-Weyl representation of density matrices

Jingmei Chang, Meiyu Cui, Ting-Gui Zhang and Shao-Ming Fei

Abstract

Separability is an important problem in theory of quantum entanglement. By using the Bloch representation of quantum states in terms of the Heisenberg-Weyl observable basis, we present a new separability criterion for bipartite quantum systems. It is shown that this criterion can be better than the previous ones in detecting entanglement. The results are generalized to multipartite quantum states.
