Abstract

A CHSHq game is a generalization of the standard two player CHSH game, having q different input and output options. In contrast to the binary game, the best classical and quantum winning strategies are not known exactly. In this paper we provide a constructive classical strategy for winning a CHSHq game, with q being a prime. Our construction achieves a winning probability better than frac{1}{22}q^{-frac{2}{3}}, which is in contrast with the previously known constructive strategies achieving only the winning probability of O\(q-1\).
