"The Complexity of Nash Equilibria,", It also suggests that the Nash equilibrium may not be an accurate prediction of behavior in all situations. Daskalakis's research emphasizes the need for new, computationally meaningful methods for modeling strategic behavior in complex systems such as those encountered in financial markets, online systems, and social networks.
Players with access to quantum resources can outperform classical ones. This will lead to novel joint strategies, impossible to achieve classically. Moreover, some of these strategies represent equilibrium points, leading to the notion of quantum/no-signalling Nash equilibrium.
