Abstract: The infinite-ranged quantum XY spin glass in a transverse field with arbitrary spin is investigated via the replica approach using the Matsubara formalism. The equation for the phase diagram is calculated in the replica symmetric and static (with respect to the Matsubara time) approximations. The phase diagrams for a few spin values are obtained.
