Fujitsu Digital Annealer boosts industrial solver selection, study finds

A head-to-head benchmark of industrial scheduling problems reveals the potential of the Fujitsu Digital Annealer alongside established quantum platforms from IBM Quantum and D-Wave, according to a new study. Researchers rigorously tested these approaches and a classical solver, using a real-world variant of the Job-Shop Scheduling Problem provided by Siemens AG, focusing on practical utility rather than simply claiming speedups. The work demonstrates that hardware-software co-design is essential for both solution quality and scalability, a finding that highlights the need for tailored formulations…
