摘要:

本文研究了最大纠缠态的局域可纠缠性。特别是,我们关心的是对于足够大的维度,任何固定数量的MES是否可以局部区分。Fan和Tian \emph{et al.}在素数或素数幂维数下对广义Bell态和量子晶格态已经得到了两个令人满意的结果。受[Phys. Rev. A \textbf{70},022304(2004)]中方法的启发,我们构造了一个适用于任意正交基的广义扭隐形传态方案。利用这种隐形传态方案,我们得到了单向可区分的MESS集的一个充分必要条件,其中包括GBS和量子晶格态作为特殊情况。此外,我们提出了[Phys. Rev. A \textbf{92},042320(2015)]中结果的推广版本,用于任意维情况。

英文摘要:

In this work, we study the local distinguishability of maximally entangled states (MESs). In particular, we are concerned with whether any fixed number of MESs can be locally distinguishable for sufficiently large dimensions. Fan and Tian \emph{et al.} have already obtained two satisfactory results for the generalized Bell states (GBSs) and the qudit lattice states when applied to prime or prime power dimensions. We construct a general twist-teleportation scheme for any orthonormal basis with MESs that is inspired by the method used in [Phys. Rev. A \textbf{70}, 022304 (2004)]. Using this teleportation scheme, we obtain a sufficient and necessary condition for one-way distinguishable sets of MESs, which include the GBSs and the qudit lattice states as special cases. Moreover, we present a generalized version of the results in [Phys. Rev. A \textbf{92}, 042320 (2015)] for the arbitrary dimensional case.
