In the pursuit of practical quantum information processing, $q\phantom{\rule{0}{0ex}}u\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}u\phantom{\rule{0}{0ex}}m$ $a\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}l\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}g$ was devised as a quantum enhanced optimizer that aims to efficiently solve Ising problems. Various architectures using superconducting qubits have been proposed, but existing annealers are currently limited by qubit coherence time. The authors propose flexible, scalable hardware for implementing a quantum annealer, combining the long coherence times of three-dimensional circuit quantum electrodynamics with the recently proposed resonator-based Lechner-Hauke-Zoller scheme. This provides a promising physical platform to realize an annealer with improved coherence and noise resilience.
