皇冠428428娱乐娱城:One-particle loss detection of genuine multipartite entanglement
题目：One-particle loss detection of genuine multipartite entanglement
简介：We study detection of genuine multipartite entanglement based on one-particle loss operator. We obtain a criterion on detecting genuine pure tripartite entanglement.The results are then generalized to arbitrary pure multipartite states. For mixed states by using the correlation tensors of the Bloch representation of density matrices, we obtain an effective criterion of arbitrary dimensional genuine tripartite entanglement.Detailed examples are given to show that our criterion is able to detect more genuine tripartite entanglement states than some existing criteria.
