"We have been exploring quantum computing for many years. Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations."

Dr. Martin Tietze
Vice President of New Technologies at BMW Group

Quantinuum and bp are collaborating on a project aimed at modernizing how the energy sector maps the Earth's subsurface to locate oil and gas resources. The project seeks to use quantum computing to potentially compress simulation timelines while also reducing energy consumption.

JPMorganChase, alongside Argonne and Oak Ridge national labs and the University of Texas at Austin, used Quantinuum's quantum computers to tackle a complex optimization problem relevant to finance.

"Through our collaboration with Quantinuum, […] we aim to be the first in the world to identify problems that can only be solved by quantum computers, and to apply them to the social infrastructure we provide."

Ryuji Wakikawa
Head of Research Institute of Advanced Technology, SoftBank Corp.

"This partnership is about giving innovators the tools they need to solve the world's most difficult design challenges. By integrating quantum computing into today's engineering workflows, we believe we can accelerate innovation while maintaining the standards and reliability that customers trust."
