Abstract

In this paper, a class of matrix maps be preserving Hermitian are constructed. Based on these maps, for pure quantum states on any finite dimensional bipartite systems, we present a necessary and sufficient condition for separability, moreover, a new lower bound of concurrence is obtained.
