Arkhipov's theorem, graph minors, and linear system nonlocal games
Connor Paddock, Vincent Russo, Turner Silverthorne +1
The perfect quantum strategies of a linear system game correspond to certain representations of its solution group. We study the solution groups of graph incidence games, which are…

Rounding near-optimal quantum strategies for nonlocal games to strategies using maximally entangled states
Connor Paddock
We establish approximate rigidity results for several well-known families of nonlocal games. In particular, we show that near-perfect quantum strategies for boolean constraint syst…
