Abstract:
In the work of the game theorist Françoise Forges, nonsignalling correlations independently appear under the name of "belief-invariant communication equilibria". The motivation and the use of these objects are different than what we would expect in quantum information. Here, we explain and unify the two views and introduce the concept of "privacy compatible correlated equilibrium". We model, for example, situations where competing companies benefit from a correlated strategy, without revealing their trade secrets (seen as private inputs).
This is work in progress, together with Andreas Winter (UAB Barcelona) and Ashutosh Rai (University of Latvia).
