Quantum nonlocality is usually associated with entangled states by their violations of Bell-
type inequalities. However, even unentangled systems, whose parts may have been …

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 …

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 …

In this paper, we generalize the concept of strong quantum nonlocality from two aspects.
First, in a tripartite quantum system, we present a construction of strongly nonlocal quantum …

Quantum nonlocality without entanglement (Q-NWE) captures nonlocal behavior of
multipartite product states as they may entail global operation for optimal decoding of the …

Suppose a set of m-partite, m≥ 3, pure orthogonal fully separable states is given. We
consider the task of distinguishing these states perfectly by local operations and classical …

Quantum theory allows for nonlocality without entanglement. Notably, there exist bipartite
quantum measurements consisting of only product eigenstates, yet they cannot be …

Any set of states which cannot be perfectly distinguished by local operations and classical
communication (LOCC) alone can always be locally distinguished using quantum …

Apart from the Bell nonlocality, which deals with the correlations generated from the local
input-output statistics, quantum theory exhibits another kind of nonlocality that involves the …
