Abstract
In this paper, spectral Barron spaces are defined in the framework of quantum harmonic analysis. Their fundamental properties are studied. These include, among others, their completeness structure and some continuous embedding results. As an application, the existence and the uniqueness of the solution of a Schr\"odinger-type equation is proved.
