    "abstract": "The approximation of matrices to the sum of tensor products of Hermitian\nmatrices is studied. A minimum decomposition of matrices on tensor space\n$H_1\\otimes H_2$ in terms of the sum of tensor products of Hermitian matrices\non $H_1$ and $H_2$ is presented. From this construction the separability of\nquantum states is discussed.",
