#### Abstract

A protocol for considering decoherence in quantum games is presented. Results for general two-player, twostrategy quantum games subject to decoherence are derived and some specific examples are given. Decoherence in other types of quantum games is also considered. As expected, the advantage that a quantum player achieves over a player restricted to classical strategies is diminished for increasing decoherence but only vanishes in the limit of maximum decoherence when the results of the game are randomized.
