| 英文摘要 | A bipartite subspace S is called strongly positive-partial-transpose (PPT) unextendible if for every positive integer k, there is no PPT operator supporting on the orthogonal complement of S-circle times k. We show that a subspace is strongly PPT unextendible if it contains a PPT-definite operator (a positive semidefinite operator whose partial transpose is positive definite). Based on these, we are able to propose a simple criterion for verifying whether a set of bipartite orthogonal quantum states is indistinguishable by PPT operations in the many-copy scenario. Utilizing this criterion, we further point out that any entangled pure state and its orthogonal complement cannot be distinguished by PPT operations in the many-copy scenario. On the other hand, we investigate that the minimum dimension of strongly PPT-unextendible subspaces in an m circle times n system is m + n - 1, which involves a generalization of the result that non-positive-partial-transpose subspaces can be as large as any entangled subspace |
