Vern Paulsen: Quantum chromatic numbers
Vern Paulsen, University of Houston
The chromatic number of a graph has a description as the classical value of a three-person game. If instead one plays a quantum version of this game, then this yields a smaller value--the quantum chromatic number of the graph. However, using the Algebraic Quantum Field Theory (AQFT) model could yield a larger set of quantum correlations, and a different value for the quantum chromatic number.
