Abstract: We perform a detailed analysis of the possible violation of various Bell-type inequalities for systems of vector boson-antiboson pairs. Considering the general case of an overall scalar state of the bipartite system, we identify two distinct classes of such states, and determine the joint probabilities of spin measurement outcomes for each them. We calculate the expectation values of the CHSH, Mermin and CGLMP inequalities and find that while the generalised CHSH inequality is not expected to be violated for any of the scalar states, in the case of the Mermin and CGLMP inequalities the situation is different -- these inequalities can be violated in certain scalar states while they cannot be violated in others. Moreover, the degree of violation depends on the relative speed of the two particles.

We present two sharp empirical Bernstein inequalities for symmetric random matrices with bounded eigenvalues. By sharp, we mean that both inequalities adapt to the unknown variance in a tight manner.

Time series and the meaning of quantum non-locality [55.2480439325792]
The derivation of Bell's inequalities gives precise meaning to the idea of quantum non-locality. It also makes evident why using it for faster than light signaling is impossible. It is demonstrated that series of outcomes, even if they violate Bell's inequalities, can be always embedded in a set of factual and counter-factual data.

Non-equilibrium dynamics of charged dual-unitary circuits [44.99833362998488]
interplay between symmetries and entanglement in out-of-equilibrium quantum systems is currently at the centre of an intense multidisciplinary research effort. We show that one can introduce a class of solvable states, which extends that of generic dual unitary circuits. In contrast to the known class of solvable states, which relax to the infinite temperature state, these states relax to a family of non-trivial generalised Gibbs ensembles.

In a measurement in which some variables are tested, other variables, not tested, have no defined value. It is proved that the correct conclusion of the violation of the CHSH inequality is different.

When three or more particles are considered, quantum correlations can be stronger than correlations generated by so-called hybrid local hidden variable models. We provide an exhaustive classification of Bell inequalities to characterize various hybrid scenarios in four- and five-particle systems.

The hypothesis from which Bell's inequalities are derived differ according to the probability space used to write them. The violation of Bell's inequalities can, alternatively, be explained assuming that the hidden variables do not exist at all.

Generalizing optimal Bell inequalities [0.0]
Bell inequalities are central tools for studying nonlocal correlations and their applications in quantum information processing. We develop a method to characterize Bell inequalities under constraints, which may be given by symmetry or other linear conditions. This allows to search systematically for generalizations of given Bell inequalities to more parties.
