摘要

Multipartite entanglement was not only an interesting phenomenon in quantum physics,but also a key resource in quantum information theory,which can allow for novel quantum advantages in quantum information processing.One of the most striking phenomena in multipartite entangled systems is that even if one acquires complete knowledge of the entire system,one can not claim to acquire all the knowledge of its subsystems [1].In particular,for a maximally or genuinely entangled multipartite pure state,its reduced subsystems may be maximally mixed ones.
