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…
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…
Partial Recovery of Quantum Entanglement
Runyao Duan, Yuan Feng, Mingsheng Ying
Suppose Alice and Bob try to transform an entangled state shared between them into another one by local operations and classical communications. Then in general a certain amount of…
An Equivalence of Entanglement-Assisted Transformation and Multiple-Copy Entanglement Transformation
Runyao Duan, Yuan Feng, Mingsheng Ying
We examine the powers of entanglement-assisted transformation and multiple-copy entanglement transformation. First, we find a sufficient condition of when a given catalyst is usefu…
