Nonlocal sets of orthogonal product states (OPSs) are widely used in quantum protocols
owing to their good property. In Phys. Rev. A 101, 062329 (2020), the authors constructed …

An orthogonal product basis of a composite Hilbert space is genuinely nonlocal if the basis
states are locally indistinguishable across every bipartition. From an operational point of …

Strong quantum nonlocality was introduced recently as a stronger manifestation of
nonlocality in multipartite systems through the notion of local irreducibility in all bipartitions …

Recently, much attention have been paid to the constructions of nonlocal multipartite
orthogonal product states. Among the existing results, some are relatively complex in …

It is known that there exist sets of pure orthogonal product states which cannot be perfectly
distinguished by local operations and classical communication (LOCC). Such sets are …

A set of multipartite orthogonal product states is strongly nonlocal if it is locally irreducible in
every bipartition, which shows the phenomenon of strong quantum nonlocality without …

Recently, much attention has been paid to the construction of nonlocal sets. The existence of
nonlocal sets gives rise to the research on the entanglement-assisted discrimination. We first …

In multipartite systems, great progress has been made recently on the study of strong
quantum nonlocality without entanglement. However, the existence of orthogonal product …

Contextuality has been identified as a potential resource responsible for the quantum
advantage in several tasks. It is then necessary to develop a resource-theoretic framework …

Abstract Recently, Halder et al (2019 Phys. Rev. Lett. 122 040403) proposed the concept of
strong nonlocality without entanglement: an orthogonal set of fully product states in …
