Webmatrix representations. Although the Bell-CHSH inequality turns out to be violated, the size of the violation is different for different representations, the maximum vio-lation being given by Tsirelson’s bound. The feature relies on a pairing mechanism between the modes of the entangled state employed to test the Bell-CHSH inequality. 1 ... WebWe develop a novel approach to Bell inequalities based on a constraint that the correlations exhibited by local variable theories must satisfy. This is used to construct a family of Bell inequalities for bipartite quantum systems of arbitrarily high dimensionality which are strongly resistant to noise. In particular, our work gives an analytic ...
