Entanglement-assisted transformation is asymptotically equivalent to multiple-copy transformation
Runyao Duan, Yuan feng, Mingsheng Ying
We show that two ways of manipulation of quantum entanglement, namely, entanglement-assisted local transformation [D. Jonathan and M. B. Plenio, Phys. Rev. Lett. {\bf 83}, 3566 (19…
Unambiguous discrimination of mixed quantum states
Chi Zhang, Yuan Feng, Ming Sheng Ying
In this paper, we consider the problem of unambiguous discrimination between a set of mixed quantum states. We first divide the density matrix of each mixed state into two parts by…
Efficiency of Deterministic Entanglement Transformation
Runyao Duan, Yuan Feng, Zhengfeng Ji +1
We prove that sufficiently many copies of a bipartite entangled pure state can always be transformed into some copies of another one with certainty by local quantum operations and…
Optimal conclusive discrimination of two states can be achieved locally
Zhengfeng Ji, Hongen Cao, Mingsheng Ying
This paper constructs a LOCC protocol that achieves the global optimality in conclusive discrimination of any two states with arbitrary a priori probability. This can be interprete…
Comparability of multipartite entanglement
Zhengfeng Ji, Runyao Duan, Mingsheng Ying
We prove, in a multipartite setting, that it's always feasible to exactly transform a genuinely -partite entangled state with sufficient many copies to any other -partite sta…
Multiple-copy entanglement transformation and entanglement catalysis
Runyao Duan, Yuan Feng, Xin Li +1
We prove that any multiple-copy entanglement transformation [S. Bandyopadhyay, V. Roychowdhury, and U. Sen, Phys. Rev. A \textbf{65}, 052315 (2002)] can be implemented by a suitabl…
