A note on the entanglement witness of bipartite quantum states
摘要
Abstract
Based on the existing conclusions on entanglement witness of bipartite states, entanglement witnesses of bipartite quantum states are further discussed. Firstly,in light of a decomposition of a self-adjoint operator,characterization of an entanglement witness is given,and some properties of entanglement witnesses are proved. An example is taken to illustrate the judgment of optimal entanglement witness. Finally,the optimal entanglement witnesses are discussed and a judgment of optimal indecomposable entanglement witness is presented.关键词
