abstract:
On a tensor product of separable complex Hilbert space, every SOT-inseparable positive operator can be detected by an SOT-inseparability witness.In this paper, the relations of different SOT-inseparability witnesses is discussed.The necessary and sufficient conditions are given for two witnesses to be comparable, to be equivalent, to be optimal, to detect some common SOT-inseparable positive operators, and to detect no common SOT-inseparable positive operators, respectively.
