• The federal funding supports critical R&D and U.S. quantum semiconductor manufacturing capabilities needed to scale fault-tolerant trapped-ion quantum computing.
• Company partnering with GlobalFoundries to fabricate next-gen ion traps and control electronics, and Monarch Quantum to develop and manufacture reliable lasers and optical components.

Washington, D.C. – September 8, 2026 – Quantinuum (Nasdaq: QNT), a leading quantum computing company, today announced it has finalized an agreement with the U.S. Department of Commerce’s CHIPS Research and Development Office for $100 million in federal funding deployed through the CHIPS and Science Act. The award, which follows a letter of intent announced in May, supports R&D and U.S. quantum semiconductor manufacturing capabilities needed to deploy large-scale, fault-tolerant trapped-ion quantum computers.

Quantinuum, which was the only company with a trapped-ion based architecture to be awarded CHIPS R&D funding, develops the world’s most accurate commercial¹ computers with industry-leading error correction fidelity.²  The company leverages established semiconductor manufacturing processes to help ensure reliability, repeatability, and scalability of the company’s current and future quantum computers.

“This award is a validation of Quantinuum’s leadership in trapped-ion quantum computing," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Together with our domestic partners, we are building the technology and supply-chain foundation needed to scale fault-tolerant systems and strengthen America's leadership in this strategically important field.”        

The award will support R&D that the company expects to help strengthen and diversify its supply chain, adding onshore partners GlobalFoundries and Monarch Quantum. GlobalFoundries will be one of several of Quantinuum’s foundries enlisted to fabricate its next-generation ion traps and other electronics, specifically focused on using 300mm wafer technology; Monarch Quantum plans to develop and manufacture scalable, reliable lasers and optical components required for Quantinuum’s trapped-ion systems.

“As quantum computing moves closer to commercial scale, manufacturing will be critical to unlocking its full potential,” said Tim Breen, CEO of GlobalFoundries. “GlobalFoundries is proud to partner with Quantinuum to help scale their trapped-ion technology. By bringing our expertise in high-volume, differentiated semiconductor manufacturing, we're helping create a path to more scalable, reliable quantum hardware and advancing the next generation of American innovation.”

“The road to large-scale, trapped-ion quantum computers relies on moving away from complex, sprawling optical setups to scalable, reliable integrated photonics engines," said Dr. Timothy Day, CEO of Monarch Quantum. "We are honored to expand our partnership with Quantinuum to advance their hardware roadmap and to help strengthen U.S. leadership in quantum computing manufacturing and supply chain resilience.”

Together, these efforts are intended to reduce system complexity and improve component robustness, reliability, and reproducibility, ultimately supporting the continued scaling of trapped-ion quantum computers, while strengthening domestic capability across critical photonics and semiconductor manufacturing.
