Abstract:
We formulate and prove Bell's inequalities in the realm of JB$^*$ triples and JB$^*$ algebras. We show that the maximal violation of Bell's inequalities occurs in any JBW$^*$ triple containing a nonassociative $2$-Peirce subspace. Moreover, we show that the violation of Bell's inequalities in a nonmodular JBW$^*$ algebra and in an essentially nonmodular JBW$^*$ triple is generic. We describe the structure of maximal violators and its relation to the spin factor. In addition, we present a synthesis of available results based on a unified geometric approach.
