We study here the dynamic susceptibility of a model quantum glass. A statistical mechanical treatment, based on a mean-field analysis of the transverse Ising model, is able to account for the competition between disorder and frustration, on the one hand, and quantal fluctuations on the other. Our results derived for the dynamic susceptibility are in qualitative agreement with experimental measurements on a recently studied dipolar-coupled quantum glass, namely LiHox YL-xF4 , whose quantum term can be manipulated in the laboratory.
