A quantum-thermal annealing method using a cluster-flip algorithm is studied in the two-dimensional spin-glass model. The temperature (T) and the transverse field (Γ) are decreased simultaneously with the same rate along a linear path on the T-Γ plane. We found that the additional pulse of the transverse field to the frozen local spins produces a good approximate solution with a low computational cost.
