Sufficient conditions of entanglement for tripartite and higher dimensional multipartite qubit density matrixes
We give the new sufficient conditions of entanglement for multipartite qubit density matrixes. We discuss in detail the case for tripartite qubit density matrixes. As a criterion in concrete applications, its steps are quite simple. and easy to operate. Some examples and discussions are given.
