Guess Your Neighbor’s Input: A Multipartite Nonlocal Game with No Quantum Advantage
We present a multipartite nonlocal game in which each player must guess the input received by his neighbour. We show that quantum correlations do not perform better than classical ones at this game, for any prior distribution of the inputs. There exist, however, input distributions for which general no-signalling correlations …
