论文摘要
超导量子计算的一个重要挑战是，需要使用准二维制造过程对许多设备进行物理磨合。量子退火处理器的设计和制造的最新进展使数千吨位的成对连通性提高了。这样的好处是，对于每种逻辑旋转，使用较少的物理Qub来进行少量的优化问题。在这里，我们证明了这种进步在最小化三维自旋玻璃的能量的问题中的好处。将上一代D-WAVE 2000Q系统与新优势系统进行比较，我们观察到解决方案时间的缩放时间改进，并提高了多个图形嵌入的一致性。
An important challenge in superconducting quantum computing is the need to physically couple many devices using quasi-two-dimensional fabrication processes. Recent advances in the design and fabrication of quantum annealing processors have enabled an increase in pairwise connectivity among thousands of qubits. One benefit of this is the ability to minor-embed optimization problems using fewer physical qubits for each logical spin. Here we demonstrate the benefit of this progress in the problem of minimizing the energy of three-dimensional spin glasses. Comparing the previous generation D-Wave 2000Q system to the new Advantage system, we observe improved scaling of solution time and improved consistency over multiple graph embeddings.
