The probability of success of quantum annealing can be improved significantly
by pausing the annealer during its dynamics, exploiting thermal relaxation in a
controlled fashion. In this paper, we investigate the effect of pausing the
quantum annealing of the fully-connected ferromagnetic $ p $-spin model. We
numerically show that (i) the optimal pausing point is 60% longer than the
avoided crossing time for the analyzed instance, and (ii) at the optimal
pausing point, we register a 45% improvement in the probability of success with
respect to a quantum annealing with no pauses of the same duration. These
results are in line with those observed experimentally for less connected
models with the available quantum annealers. The observed improvement for the $
p $-spin model can be up to two orders of magnitude with respect to an isolated
quantum dynamics of the same duration.

本研究探讨了利用热松弛控制量子退火器的动力学，并通过数字分析得出，在最佳暂停点时，相较于同等时间的量子退火器，可以实现约 45% 的成功率提升，进一步证实了在其他量子退火器中所观察到的结果。
