  We show that the effective action of the quantum spherical spin glass is
invariant under a generalized form of the Becchi-Rouet-Stora-Tyutin(BRST)
supersymmetry. The Ward identities associated to this invariance indicate that
the spin glass order parameter must vanish, and as a result the annealed
average is exact in this model. We present new results for for the free energy,
entropy and specific heat. Due to quantum effects the entropy remains finite
and the specific het vanishes at zero temperature. results for the phase
diagram coincide with those obtained by different formalisms. At zero
temperature we derive the scaling behaviour with frequency of the dynamical
susceptibility.
