Entanglement as a resource to locally distinguish tripartite quantum states
Recently, Zuo et al. (Quantum Inf Process 20:382, 2021) construct the nonlocal sets of tripartite orthogonal product states with less members. Then, how much entanglement resource is sufficient to locally dist...

Quantum entanglement as a resource to locally distinguish orthogonal product states
Recently, Zhang et al. constructed one family of orthogonal product states which cannot be perfectly distinguished by local operations and classical communication (LOCC) in the

Strong quantum nonlocality for multipartite entangled states
Recently, Halder et al. (in Phys Rev Lett 122:040403, 2019) present two sets of strong nonlocality of orthogonal product states based on the local irreducibility. However, for a set of locally indistinguishabl...

Locally distinguishing multipartite orthogonal product states with different entanglement resource
Recently, entanglement-assisted state discrimination has attracted much attention. However, most of the relevant results are about the bipartite quantum states and very little is known about the multipartite c...

Using entanglement more efficiently in distinguishing orthogonal product states by LOCC
In this paper, we mainly study the problem of locally distinguishing orthogonal product states using entanglement as a resource. We present methods to improve the previous results, presented by other authors, ...

Determination of locally perfect discrimination for two-qubit unitary operations
In the study of local discrimination for multipartite unitary operations, Duan et al. (Phys Rev Lett 100(2):020503, 2008) exhibited an ingenious expression: Any two different unitary operations ...

Perfect discrimination of projective measurements with the rank of all projectors being one
In this paper, we focus on the global discrimination of projective measurements in which the rank of all projectors is one. Firstly, the relation between single-qubit observables and measurement–unitary operat...

One-way LOCC indistinguishability of maximally entangled states
In this letter, we mainly study the local indistinguishability of mutually orthogonal maximally entangled states, which are in canonical form. Firstly, we present a feasible sufficient and necessary condition ...
