| Abstract: | We discuss the Hamel base of the vector space of three-partite quantum system,and present the representation of density matrix for a three-partite quantum system.We prove that if the density matrix of arbitrary state in a three-partite quantum system is separable,the Forbenius norm of its constructive matrix is not more than 1,and examples are given to support this conclusion. |
