Title: Values of quantum non-local games

Abstract: I will describe a general setup that allows expressing the value of a quantum-to-quantum non-local game with respect to a certain quantum resource as the norm of an associated game tensor when the latter is viewed as an element of a canonical operator space based on the trace class operators, induced by the given resource. I will apply the setup in particular to the case of the resource of all quantum commuting no-signalling correlations, which will permit obtaining formulas for the quantum commuting value of a game as a maximal operator space tensor product norm. The talk is based on a joint work with J. Crann, R. Levene and L. Turowska.
