S.J.D.: Mini-maximizing two qubit quantum computations

Two qubit quantum computations are viewed as two player, strictly compet-itive games and a game-theoretic measure of optimality of these computations is developed. To this end, the geometry of Hilbert space of quantum computa-tions is used to establish the equivalence of game-theoretic solution concepts of Nash equilibrium and mini-max outcomes in games of this type, and quantum mechanisms are designed for realizing these mini-max outcomes.
