Quantinuum and Aramco signed a non-binding memorandum of understanding on Sept. 3, 2026, in Riyadh to explore quantum computing (advanced computing using quantum mechanics) applications in energy and digital transformation. The companies intend to conduct preliminary technical onboarding, exchange knowledge, identify Aramco challenges suitable for quantum research, assess future systems against scientific and industrial needs, and benchmark different quantum computing modalities. The initiative supports Aramco's existing efforts to apply advanced quantum technologies in the energy industry and could lead to a deeper research collaboration focused on fault-tolerant quantum computing. Quantinuum said the agreement will combine Aramco's scientific and engineering expertise with its integrated hardware and software capabilities.
