Bell’s inequalities versus teleportation: What is nonlocality?
Physical Review Letters, 1994Summary: The nonlocality responsible for violations of Bell's inequalities is not equivalent to that used in teleportation, although they probably are two aspects of the same physical property. There are mixed states which do not violate any Bell type inequality, but still can be used for teleportation.

Nonlocal Theories Satisfying Bell's Inequality
Il Nuovo Cimento B Series 11, 1978Bell’s inequality is well known to be a necessary consequence of Einstein locality. We show, however, that the two best-knownnonlocal theories (Newtonian dynamics and the de Broglie-Bohm nonlocal hidden-variable model) always satisfy Bell’s inequality. The domain of validity of the latter is, therefore, much broader than hitherto believed and the only ...

Nonlocal interactions and Bell's inequality
Il Nuovo Cimento B Series 11, 1976We show that natural extensions of the local hidden-variable theories to include nonlocal effects still lead to a full validity of Bell's inequality. It is conjectured that the essential point expressed by this inequality is not locality, but the wave-particle dualism.

Multipartite quantum nonlocality using functional Bell inequalities
Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009We show that arbitrary functions of continuous variables can be used to generate tests of local hidden variable theories. The effect of nonideal detectors and noise is included, revealing that optimized functional inequalities are robust.

The Bell inequalities and nonlocality
Physics Letters A, 1982Abstract The Bell inequalities give a criterion for nonlocality in theories where it is permissible to speak of the values of unmeasured variables. It is shown that the same criterion may be used in theories where this is not permissible. According to the criterion, quantum mechanics is nonlocal.

Quantum nonlocality and Bell's inequalities
Annals of the Israel Physical Society, 1996A number of additional assumptions is discussed playing a role in derivations of the Bell inequalities along with the locality condition. An analogy between quantum mechanics and statistical thermodynamics is exploited to demonstrate that the ex istence of conditional probabilities p(ai|,Lambda)generally assumed in stochastic hidden variables theories,

Characterizing Bell nonlocality and EPR steering
Science China Physics, Mechanics & Astronomy, 2018Bell nonlocality and Einstein-Podolsky-Rosen (EPR) steering are very important quantum correlations in composite quantum systems. Bell nonlocality of a bipartite state is observed in some local quantum measurements, while EPR steering was first observed by Schrodinger in the context of famous EPR paradox.

Objectivity, nonlocality, and the Bell inequalities
Physics Letters A, 1983It is argued that the Bell inequalities are not a specific feature of local hidden variables theories, but obtain both for local and nonlocal theories that are objectivistic. A nonobjectivistic theory is constructed reproducing the quantum mechanical correlations obtained in realisations of the Einstein-Podolsky-Rosen-Bohm experiment.
