We quantise the generalised Hawk-Dove Game. By restricting the strategy space
available to the players, we show that every game of this type can be extended
into the quantum realm to produce a Pareto optimal evolutionarily stable
strategy. This equilibrium replaces the inefficient classical one when the
entanglement prepared in the game exceeds a critical threshold value, which we
derive analytically.Comment: 7 pages, 2 figures, submitted for review, comments welcom
