摘要:
We present a way to construct indecomposable entanglement witnesses from any permutations pi with pi(2) not equal id for any finite dimensional bipartite systems. Some new bounded entangled states are also found, which can be detected by such witnesses while cannot be distinguished by PPT criterion, realignment criterion, etc.
