We use quantum Monte Carlo methods and various analytic approximations tosolve the Ising spin-glass model in a transverse field in the disordered phase.We focus on the behavior of the frequency dependent susceptibility of thesystem above and below the critical field . We establish the existence of anexact equivalence between this problem and the single-impurity Kondo model atthe quantum critical point. Our predictions for the long-time dynamics of themodel are in good agreement with experimental results on$LiHo_{0.167}Y_{0.833}F_4$.Comment: 4 pages Latex. 2 postscript figure
