The U.S. government has committed $300 million in funding to three quantum computing companies—D-Wave Quantum, Rigetti Computing, and Quantinuum—providing each with $100 million under research and development grants through the CHIPS Act. This initiative, announced on Tuesday, includes the Department of Commerce acquiring minority equity stakes in all three firms as part of a broader effort to bolster domestic semiconductor and advanced hardware supply chains.
The investment aims to accelerate the scale-up of quantum computing technologies, a sector viewed as critical for maintaining U.S. competitiveness in next-generation computing. Following the announcement, shares in the companies saw positive movement: Quantinuum increased 1.7% to $50.47, D-Wave rose 6.6% to $17.70, and Rigetti’s stock climbed 4% to $15.81.
Rigetti plans to allocate the new resources toward resolving technical challenges related to scaling superconducting quantum processors. This includes expanding cryogenic infrastructure and increasing manufacturing efficiency at specialized facilities to support broader production.
D-Wave, headquartered in British Columbia, intends to focus its funds on advancing microelectronics research and development. The company will prioritize prototyping advanced semiconductor technologies aimed at creating scalable, high-performance quantum hardware.
Quantinuum’s funding is directed at developing scalable, reliable integrated photonics engines through partnerships with domestic manufacturers. The company confirmed plans to collaborate with GlobalFoundries to produce next-generation ion traps and related electronics, as well as with Monarch Quantum for the fabrication of integrated lasers and optical components essential to its quantum systems.
Separately, GlobalFoundries finalized a separate $375 million agreement with the U.S. government to support the expansion of domestic quantum manufacturing capabilities. The company stated the funding will help secure critical technologies necessary for building scalable quantum processing units within the United States.
These investments reflect a growing government emphasis on fostering a robust domestic quantum technology ecosystem, responding to global technological competition and supply chain concerns. The Commerce Department’s minority stakes in the companies indicate an increased federal role in the strategic development of advanced quantum computing infrastructure.
