We introduce a novel technique to give bounds to the entangled value of non-local games. The technique is based on a class of graphs used by Cabello, Severini and Winter in 2010.

The lower bound uses the famous Lovasz theta number and is efficiently computable; the upper one is based on the quantum independence number, which is a quantity used in the study of entanglement-assisted channel capacities and graph homomorphism games.

Joint work with Andrè Chailloux, Laura Mancinska and Simone Severini.
