Non-binding Memorandum of Understanding (MOU) aims to support innovation and operational excellence within the energy sector.
‍
Riyadh, August 31, 2026: Quantinuum, a leading quantum computing company, today announced the signing of a non-binding MOU with Aramco, one of the world’s leading integrated energy and chemicals companies, to explore a series of industrial use cases, enhance quantum computing capabilities, and prepare for a potential research collaboration focused on fault-tolerant quantum computing.

Under the MOU, the companies intend to undertake preliminary technical onboarding and engage in knowledge exchange activities. They will also identify Aramco’s challenges that may be suitable for quantum computing research with an emphasis on solving complex problems in energy and digital transformation. The collaboration aims to assess how future generations of quantum systems may address relevant scientific and industrial challenges, and to benchmark different quantum computing modalities.

The collaboration complements Aramco’s existing initiatives to position itself as a leader in the application of advanced quantum technologies within the energy industry, reinforcing its efforts towards supporting the digital transformation of the sector and contributing to the evolving quantum computing roadmap for the energy industry.

“Organizations that expect to benefit from quantum computing need to begin developing their expertise, algorithms and workflows today,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “This MOU creates a framework for Quantinuum and Aramco to exchange expertise, identify important industrial challenges and prepare for a deeper research collaboration. By combining Aramco’s scientific and engineering knowledge with Quantinuum’s integrated hardware and software capabilities, we aim to build a strong foundation for research across future generations of quantum computing.”
