Comment on: "A quantum approach to static games of complete information''

Abstract

Recently Marinatto and Weber introduced an interesting new scheme for quantizing games, and applied their scheme to the famous game 'Battle of the Sexes'. In this Comment we make two observations: (a) the overall quantization scheme is fundamentally very similar to a previous scheme proposed by Eisert et al., and (b) in contrast to a main claim of the paper, the quantum Battle of the Sexes game does not have a unique solution - a similar dilemma exists in both the classical and the quantum versions.
