Quantinuum has finalized an agreement with the CHIPS Research and Development Office of the U.S. Department of Commerce for a $100 million federal grant under the CHIPS and Science Act. The award, following a letter of intent announced in May, will support research and development and U.S. manufacturing capacity for quantum semiconductors used in large-scale, fault-tolerant trapped-ion quantum computers. Quantinuum says it is the only trapped-ion architecture company to receive CHIPS R&D funding and develops commercial quantum computers it describes as the world’s most accurate, based on leading error-correction fidelity. GlobalFoundries will manufacture next-generation ion traps and control electronics, with emphasis on 300-millimeter wafer technology, while Monarch Quantum will develop and manufacture scalable lasers and optical components. The program is intended to diversify Quantinuum’s supply chain, simplify system designs and improve component robustness, reliability and reproducibility. The company says these efforts will strengthen U.S. capabilities in photonics and semiconductor manufacturing and support further scaling of trapped-ion systems. Quantinuum employs more than 800 people worldwide and is headquartered in Broomfield, Colorado, with additional facilities in the United States, the United Kingdom, Germany, Japan, Qatar and Singapore. The company cautioned that its forward-looking statements remain subject to economic, competitive, governmental and technological risks.
