On quantum symmetries of graphs
Preprint, 2026
Let G be a simple finite graph, and let U(G) be the related quantum graph. We study the game algebra C(Qut(U(G))) of quantum automorphism of U(G). Moreover, we prove that for any graph G with |V(G)|≥3, the quantum graph U(G) admits nonlocal symmetry, meaning that there exists a perfect quantum no-signaling correlation
