论文摘要
我们提出了抵绝热的反向退火，这是一种新型的量子退火协议，该协议扩展了反向退火的应用范围，以便于先前无法访问的短时域。这是通过利用低阶嵌套换向器扩展的近似灭绝热驾驶来实现的。在这项工作中，我们将这种新技术的性能与无助的反向退火的比较研究提供了相当的研究，例如地面富达等指标和解决方案的时间。我们提供了对反浸润反向退火的能量成本的定量度量，并表明即使使用局部抵绝热的潜力也可以进行重大改进，从而为在近期量子设备中实现实施的方式铺平了道路。
We present Counterdiabatic Reverse Annealing, a novel quantum annealing protocol that extends the range of application of reverse annealing to the previously inaccessible short-time domain. This is achieved by exploiting approximate counterdiabatic driving expanded in low-order nested commutators. In this work, we offer a comparative study of the performance of this new technique to that of unassisted reverse annealing in terms of metrics such as the ground-state fidelity and the time to solution. We provide a quantitative measure of the energetic cost of counterdiabatic reverse annealing and show that significant improvements are possible even using local counterdiabatic potentials, paving the way toward the experimental implementation in near-term quantum devices.
