Quantum violation of the Suppes-Zanotti inequalities and "contextuality"
arXiv:2101.10167 · doi:10.1007/s10773-021-04850-9
Abstract
The Suppes-Zanotti inequalities involving the joint expectations of just three binary quantum observables are (re-)derived by the hull computation of the respective correlation polytope. A min-max calculation reveals its maximal quantum violations correspond to a generalized Tsirelson bound. Notions of "contextuality" motivated by such violations are critically reviewed.
