A quantum version of the ultimatum game is studied. Both a restricted version with classical moves and the unitary version are considered. With entangled initial states, Nash equilibria in quantum games are in general different from those of classical games. Quantum versions might therefore be useful as a framework for modeling deviations from classical Nash equilibrium in experimental games.
