A current research theme in quantum graph theory is to determine which classical/quantum groups can occur as the classical/quantum automorphism group of finite graphs. One question in this direction is to determine how far the classical and quantum automorphism groups can be apart. In this talk, I will present a class of graphs which have trivial automorphism group and non-trivial quantum automorphism group, thereby answering a question asked by several authors in recent years. The construction is inspired by linear constraint system games in quantum information theory. This talk is based on joint work<https://arxiv.org/abs/2311.04889> with David E. Roberson and Simon Schmidt.
