QIAW02 - New trends at the intersection of quantum information theory, quantum groups and operator algebras

Nonlocal games are a foundational tool for understanding entanglement and constructing quantum protocols in settings with spatially separated quantum devices. Recently,Kalai et al. defined a cryptographic compilation procedure for nonlocal games. It translates a (two-player) nonlocal game into a single-player game, using cryptography to simulate the spatial separation between the players. This talk will be about the quantum value of such compiled nonlocal games. We will discuss techniques for bounding the quantum value and see when the value is preserved under the compilation procedure. This talk is based on joint work with Alexander Kulpe, Giulio Malavolta, Connor Paddock and Michael Walter.
