QIAW02 - New trends at the intersection of quantum information theory, quantum groups and operator algebras Consider nonlocal games, but allow for quantum questions and answers. We call these objects $\textbf{quantum games}$. It turns out the typical definitions from the nonlocal games literature can be extended and many of the typical results still hold in this quantum setting. The analogies to the typical setting can be seen clearly using string diagrams! This talk contains many diagrams. We use string diagrams to introduce extended definitions of games, strategies, correlations, and synchronicity. We introduce the new notion of $\textbf{complete synchronicity}$ (which is to synchronicity as complete positivity is to positivity), and we show that perfect correlations and strategies for completely synchronous quantum games must be completely synchronous. When the graph homomorphism game is extended to quantum graphs, we get a completely synchronous game, whose perfect strategies are quantum graph homomorphisms!- This work is inspired by Musto, Reutter, and Verdon’s
**A compositional approach to quantum functions**. It can also refer to the textbook**Categories for Quantum Theory**by Heunen and Vicary if you are seeking a reference for using string diagrams in quantum information.
