We investigate the computational efficiency and thermodynamic cost of the D-Wave quantum annealer under reverse-annealing with and without pausing. Our demonstration on the D-Wave 2000Q annealer shows that the combination of reverse-annealing and pausing leads to improved computational efficiency while minimizing the thermodynamic cost compared to reverse-annealing alone. Moreover, we find that the magnetic field has a positive impact on the performance of the quantum annealer during reverse-annealing but becomes detrimental when pausing is involved. Our results, which are reproducible, provide strategies for optimizing the performance and energy consumption of quantum annealing systems employing reverse-annealing protocols.
我们研究了在有停顿和无停顿的反向退火情况下，D-Wave量子退火器的计算效率和热力学成本。我们在D-Wave 2000Q退火器上的演示表明，与单独的反向退火相比，反向退火和停顿相结合可提高计算效率，同时将热力学成本降至最低。此外，我们发现磁场在反向退火期间对量子退火器的性能有积极影响，但在涉及停顿时则会产生不利影响。我们的结果具有可重复性，为优化采用反向退火协议的量子退火系统的性能和能耗提供了策略。
