SUMMARY:A bound on the quantum value of all compiled nonlocal games - Simo

DESCRIPTION:Nonlocal games are a foundational tool for understanding entan
 glement and constructing quantum protocols in settings with spatially sepa
 rated quantum devices. Recently\,Kalai et al. defined a cryptographic comp
 ilation procedure for nonlocal games. It translates a (two-player) nonloca
 l game into a single-player game\, using cryptography to simulate the spat
 ial separation between the players. This talk will be about the quantum va
 lue of such compiled nonlocal games. We will discuss techniques for boundi
 ng the quantum value and see when the value is preserved under the compila
 tion procedure.\nThis talk is based on joint work with Alexander Kulpe\, G
 iulio Malavolta\, Connor Paddock and Michael Walter.
