Readiness of Quantum Optimization Machines for Industrial Applications

With quantum computing technologies nearing the era of quantum supremacy, and of commercialization, near-term devices need to be tested with application-driven benchmarks. Here the authors contribute a comprehensive assessment of the readiness of quantum optimization for a real industrial problem: fault diagnosis in digital circuits. From the perspective of physics and application, they investigate the impact of next-generation quantum annealers in direct comparison to state-of-the-art classical heuristics. Although more challenging in nature, these real-world problems provide insight on the real-world performance of quantum optimization machines.
