We study the perfectly local indistinguishability of multipartite product states. Firstly, we follow the method of Zhang et al. (Phys Rev A 93:012314, 2016) to give another more concise set of 2n − 1 orthogonal product states in Cm ⊗ Cn (4 ≤ m ≤ n) which can not be distinguished by local operations and classical communication. Then we use the(More)
We study the problem of distinguishing maximally entangled quantum states by using local operations and classical communication (LOCC). A question of fundamental interest is whether any three maximally entangled states in C ⊗ C(d ≥ 4) are distinguishable by LOCC. In this paper, we restrict ourselves to consider the generalized Bell states. And we prove that(More)
We study the unextendible maximally entangled bases (UMEB) in C d ⊗ C d and connect the problem to the partial Hadamard matrices. We show that for a given special UMEB in Cd ⊗ C d , there is a partial Hadamard matrix which cannot be extended to a Hadamard matrix in Cd . As a corollary, any (d − 1) × d partial Hadamard matrix can be extended to a Hadamard(More)
