The most general class of non-locality criteria for N-partite d-chotomic systems with k number of measurement settings is derived under the constraint of measurement symmetries. It is the complete characterisation of the multi-partite non-locality when the correlation is assumed to be symmetric under the choice of measurement settings. The generalized non-locality condition is obtained using the correlation functions, which are derived from Fourier analysis of probability spectrums. It is found… Expand

Generalized nonlocality criteria under the correlation symmetry
The class of correlation for the most generalized Bell scenario considering N-partite d-chotomic system with k number of measurements is derived under the constraint of measurement symmetries. TheExpand
Noise resistance of activation of the violation of the Svetlichny inequality
In this paper, we analyze the activation of the violation of the Svetlichny inequality in GHZ states in the presence of noise. We take into account bit flip, phase flip, amplitude damping andExpand
Bell-Type Correlation at Quantum Phase Transitions in Spin-1 Chain
TLDR
Diverse classes of quantum phase transitions in the spin-1 model are identified precisely through the evaluation of the first and the second moments of the generalized Bell correlations. Expand
Noise-adaptive test of quantum correlations with quasiprobability functions
We introduce a method for testing quantum correlations in terms of quasiprobability functions in the presence of noise. We analyze the effects of measurement imperfection and thermal environment onExpand

Detecting non-locality in multipartite quantum systems with two-body correlation functions
Bell inequalities define experimentally observable quantities to detect non-locality. In general, they involve correlation functions of all the parties. Unfortunately, these measurements are hard toExpand
Maximally Non-Local and Monogamous Quantum Correlations
We introduce a version of the chained Bell inequality for an arbitrary number of measurement outcomes and use it to give a simple proof that the maximally entangled state of two d-dimensional quantumExpand
Detecting genuine multipartite quantum nonlocality: a simple approach and generalization to arbitrary dimensions.
TLDR
A simple and intuitive approach is presented to Svetlichny's original inequality, which provides a clear understanding of its structure and of its violation in quantum mechanics, and a family of Bell-type inequalities for detecting genuine multipartite nonlocality in scenarios involving an arbitrary number of parties and systems of arbitrary dimension is derived.

TLDR
It is shown that, for any n≥2, the exclusivity principle, as derived from axioms about sharp measurements, and a technical assumption give the exact bounds predicted by quantum theory. Expand
Optimal tests of quantum nonlocality
We present a general method for obtaining all Bell inequalities for a given experimental setup. Although the algorithm runs slowly, we apply it to two cases. First, the Greenberger-Horne-ZeilingerExpand
Axiomatic approach for the functional bound of multipartite high dimensional correlation
Abstract We propose a formalism to derive the maximal bound of generalized Bell type correlation and shows that the formalism can be applied to various form of Bell functions. The Bell function isExpand
Bell-type inequalities for partial separability in N-particle systems and quantum mechanical violations.
TLDR
N-particle Bell-type inequalities under the assumption of partial separability, i.e., that the N-particles system is composed of subsystems which may be correlated in any way but which are uncorrelated with respect to each other, are derived. Expand
Maximal violation of the Collins-Gisin-Linden-Massar-Popescu inequality for infinite dimensional states.
TLDR
For very large values of d the inequality seems to reach its minimal value given by the probability constraints, which gives numerical evidence for a tight quantum Bell inequality (or generalized Csirelson inequality) for the 2x2xinfinity scenario. Expand
Test of nonlocality for a continuous-variable state based on an arbitrary number of measurement outcomes.
TLDR
It is demonstrated that CV systems can give higher violations of these Bell's inequalities than of the ones developed for two-outcome observables. Expand
