 l solution of the transverse field Sherrington-Kirkpatrick quantum spin gl
 ass model\, by implementing the continuous-time Monte Carlo method in the 
 presence of full replica symmetry breaking. We extract the complete numeri
 cally exact phase diagram\, displaying a glassy phase with continuous repl
 ica symmetry breaking at small transverse fields and low temperatures. A p
 aramagnetic phase emerges once thermal and quantum fluctuations melt the s
 pin glass. We characterize both phases by extracting the order parameter\,
  as well as the static and dynamical local spin susceptibilities. The stat
 ic susceptibility shows a plateau in the glassy phase\, but remains smooth
  across the phase boundary\, while the shape of dynamical susceptibility v
 aries upon crossing the glass transition by reducing quantum fluctuations.
  We qualitatively compare these results to the susceptibility observed exp
 erimentally in dipole-coupled Ising magnets in a transverse magnetic field
 . Our work provides a general framework for the exact numerical solution o
 f mean field quantum glass models\, constituting an important step towards
  understanding glassiness in realistic systems. .
