We compare two different tests of quantum nonlocality, both in theoretical terms and with respect to a possible implementation in a mesoscopic circuit: Hardy's test [L. Hardy, Phys. Rev. Lett. 68, 2981 (1992)] and the Clauser-Horne-Shimony-Holt (CHSH) test, the latter including a recently discovered inequality relevant for experiments with three possible outcomes [D. Collins and N. Gisin, J. Phys. A 37, 1775 (2004)]. We clarify the geometry of the correlations defined by Hardy's equations with…

A unified view on Hardyʼs paradox and the Clauser–Horne–Shimony–Holt inequality
Bellʼs inequality fundamentally changed our understanding of quantum mechanics. Bellʼs insight that non-local correlations between quantum systems cannot be explained classically can be verified

A New Error-Modeling of Hardy’s Paradox for Superconducting Qubits and Its Experimental Verification
Hardy’s paradox (equivalently, Hardy’s non-locality or Hardy’s test) [Phys. Rev. Lett. 68, 2981 (1992)] is used to show non-locality without inequalities, and it has been tested several times using
Device-Independent bounds for Hardy's experiment.
TLDR
An analogue of Tsirelson's bound for Hardy's test of nonlocality is computed, that is, the maximum violation of locality constraints allowed by the quantum formalism, irrespective of the dimension of the system.
TSIRELSON'S PROBLEM AND KIRCHBERG'S CONJECTURE
Tsirelson's problem asks whether the set of nonlocal quantum correlations with a tensor product structure for the Hilbert space coincides with the one where only commutativity between observables
The Hardy’s nonlocality argument
Certain predictions of quantum theory are not compatible with the notion of local-realism. This was the content of Bell’s famous theorem of the year 1964. Bell proved this with the help of an
Constancy of maximal nonlocal probability in Hardy's nonlocality test for bipartite quantum systems
We give the generic form of the entangled states of a system of two spin-1 (and two spin-) particles and the appropriate set of spin observables that together exhibit maximum nonlocality under
Characterizing quantum correlations in the nonsignaling framework
Quantum correlations forms a subset of the set of nonsignaling boxes. This allows us to characterize quantum correlations as a convex combination of the extremal boxes of the nonsignaling polytope
The Inflation Technique for Causal Inference with Latent Variables
Abstract The problem of causal inference is to determine if a given probability distribution on observed variables is compatible with some causal structure. The difficult case is when the causal

TLDR
It is proved that homogeneous inequalities, involving only coincidence detection rates, cannot discriminate between quantum mechanics and local theories, which invalidates all previously used empirical tests and conjectured that quantum mechanics might be compatible with local realism.
Clauser-Horne inequality for three-state systems
We show a new Bell-Clauser-Horne inequality for two entangled three-dimensional quantum systems (socalled qutrits). This inequality is not violated by a maximally entangled state of two qutrits

It is argued that among possible nonlocal hidden-variable theories a particular class (called here “crypto-nonlocal” or CN) is relatively plausible on physical grounds. CN theories have the property

We generalize Hardy's proof of nonlocality to the case of bipartite mixed statistical operators, and we exhibit a necessary condition which has to be satisfied by any given mixed state
An experimental test of non-local realism
TLDR
This work shows by both theory and experiment that a broad and rather reasonable class of such non-local realistic theories is incompatible with experimentally observable quantum correlations, and suggests that giving up the concept of locality is not sufficient to be consistent with quantum experiments, unless certain intuitive features of realism are abandoned.
Experimental test of the violation of local realism in quantum mechanics without Bell inequalities
We report the results of an experiment in which postselected polarization-entangled photons were used to test the recent nonlocality proof by L. Hardy [Phys. Rev. Lett. 71, 1665 (1993)]. The
Realization of Hardy's thought experiment with photons.
TLDR
An experimental realization of Hardy's thought experiment is presented, using photons, that creates a striking contradiction between the predictions of quantum mechanics and local hidden variables.
Nonlocal correlations as an information-theoretic resource
It is well known that measurements performed on spatially separated entangled quantum systems can give rise to correlations that are nonlocal, in the sense that a Bell inequality is violated. They

Recently a new Bell inequality has been introduced (CGLMP,KKCZO) that is strongly resistant to noise for maximally entangled states of two d-dimensional quantum systems. We prove that a larger
