Approximate quantum 3-colorings of graphs and the quantum Max 3-Cut problem
Samuel J. Harris
We prove that, to each synchronous non-local game with and , there is an associated graph for which approximate winning strategies…
Universality of graph homomorphism games and the quantum coloring problem
Samuel J. Harris
We show that quantum graph parameters for finite, simple, undirected graphs encode winning strategies for all possible synchronous non-local games. Given a synchronous game $\mathc…
Synchronous games with -isomorphic game algebras
Samuel J. Harris
We establish several strong equivalences of synchronous non-local games, in the sense that the corresponding game algebras are -isomorphic. We first show that the game algebra o…
Schur multipliers and mixed unitary maps
Samuel J. Harris, Rupert H. Levene, Vern I. Paulsen +2
We consider the tensor product of the completely depolarising channel on matrices with the map of Schur multiplication by a correlation matrix and characte…
