Sufficient conditions of entanglement for tripartite and higher dimensional multipartite qubit density matrixes

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/91512In this paper 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 application, its steps are quite simple and easy to operate. Some examples and discussions are given.
