We introduce a density matrix decomposition of a multipartite quantum system of a finite dimension into two density matrices:a separable one and an essentially entangled one,which contains no product states components.This convex decomposition can be achieved in practice with the help of an algorithm based on linear programming,which in the general case scales polynomially with the dimension of the system.
