How much Quantum information can improve Social Welfare.
Abstract:
It has been shown in [1] that quantum resources can allow to achieve a family of Nash equilibria that can have sometimes a better social welfare while guaranteeing privacy.
We use graph games to propose a way to build non cooperative games from graph states and show how we can achieve an unlimited improvement with the quantum advices compared to the classical one. We also discuss the notion of guaranteed utility that these games provide.
This is a work in progress with Berry Groisman Michael Mc Gettrick and Marcin Pawlowski.
