  We present a scheme for playing quantum repeated 2x2 games based on the
Marinatto and Weber's approach to quantum games. As a potential application, we
study twice repeated Prisoner's Dilemma game. We show that results not
available in classical game can be obtained when the game is played in the
quantum way. Before we present our idea, we comment on the previous scheme of
playing quantum repeated games.
