  Here we first discuss briefly the quantum annealing technique. We then study
the quantum annealing of Sherrington-Kirkpatrick spin glass model with the
tuning of both transverse and longitudinal fields. Both the fields are
time-dependent and vanish adiabatically at the same time, starting from high
values. We solve, for rather small systems, the time-dependent Schrodinger
equation of the total Hamiltonian by employing a numerical technique. At the
end of annealing we obtain the final state having high overlap with the exact
ground state(s) of classical spin glass system (obtained independently).
