Abstract: Communication games consist of distributes parties attempting to jointly complete a task with restricted communication. Such games can be used to study non-classicality. This talk presents two experiments showing that restricted communications scenarios can be used to distinguish between classical and non-classical strategies. The first shows a communication games as preparation contextuality test. The second uses a parallel quantum random access code, an important type of restricted communication protocol, to show an inconditional test of non-classicality.
