Post-quantum nonlocality in the minimal triangle scenario [PDF]
New Journal of Physics, 2023 We investigate network nonlocality in the triangle scenario when all three parties have no input and binary outputs. Through an explicit example, we prove that this minimal scenario supports nonlocal correlations compatible with no-signaling and ...

Quantum Nonlocality: Multicopy Resource Interconvertibility and Their Asymptotic Inequivalence. [PDF]
Physical Review Letters, 2023 Quantum nonlocality, pioneered in Bell's seminal work and subsequently verified through a series of experiments, has drawn substantial attention due to its practical applications in various protocols.

Bounds on the smallest sets of quantum states with special quantum nonlocality [PDF]
Quantum, 2022 An orthogonal set of states in multipartite systems is called to be strong quantum nonlocality if it is locally irreducible under every bipartition of the subsystems \cite{Halder19}. In this work, we study a subclass of locally irreducible sets: the only

Strong quantum nonlocality and unextendibility without entanglement in N-partite systems with odd N [PDF]
Quantum, 2022 A set of orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition, which shows the phenomenon of strong quantum nonlocality without entanglement.

Proofs of Network Quantum Nonlocality in Continuous Families of Distributions. [PDF]
Physical Review Letters, 2022 The study of nonlocality in scenarios that depart from the bipartite Einstein-Podolsky-Rosen setup is allowing one to uncover many fundamental features of quantum mechanics. Recently, an approach to building network-local models based on machine learning

Towards a minimal example of quantum nonlocality without inputs [PDF]
Physical Review A, 2022 The network scenario offers interesting new perspectives on the phenomenon of quantum nonlocality. Notably, when considering networks with independent sources, it is possible to demonstrate quantum nonlocality without the need for measurements inputs, i ...

Genuine network quantum nonlocality and self-testing [PDF]
Physical Review A, 2021 The network structure offers in principle the possibility for novel forms of quantum nonlocal correlations, that are proper to networks and cannot be traced back to standard quantum Bell nonlocality.

Orthogonal product sets with strong quantum nonlocality on a plane structure [PDF]
Physical Review A, 2022 In this paper, we consider the orthogonal product set (OPS) with strong quantum nonlocality. Based on the decomposition of plane geometry, we present a sufficient condition for the triviality of orthogonality-preserving POVM on fixed subsystem and ...

Quantum nonlocality in the presence of strong measurement dependence [PDF]
Physical Review A, 2022 It is well known that the effect of quantum nonlocality, as witnessed by violation of a Bell inequality, can be observed even when relaxing the assumption of measurement independence, i.e.

Strong quantum nonlocality for unextendible product bases in heterogeneous systems [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 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 entanglement.
