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...

Local Discrimination of Orthogonal Product States with a Two-Qubit Maximally Entangled State
Recently, Zhang et al. raised two classes of orthogonal product states which cannot be exactly discriminated by local operations and classical communication (LOCC) in the quantum system of (2k + 1) ⊗ 2l and (3k +...

Open AccessEntanglement as a resource to distinguish orthogonal product states
It is known that there are many sets of orthogonal product states which cannot be distinguished perfectly by local operations and classical communication (LOCC). However, these discussions have left the follow...

Open AccessMinimal number of runs and the sequential scheme for local discrimination between special unitary operations
It has been shown that any two different multipartite unitary operations are perfectly distinguishable by local operations and classical communication with a finite number of runs. Meanwhile, two open question...

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...

Bound on local unambiguous discrimination between multipartite quantum states
We investigate the upper bound on unambiguous discrimination by local operations and classical communication. We demonstrate that any set of linearly independent multipartite pure quantum states can be locally...

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 ...
