PsiQuantum signed a Letter of Intent with the U.S. Department of Commerce for $100 million in proposed CHIPS and Science Act incentives to advance domestic manufacturing for photonic quantum computing components. The company said the funding, combined with private co-investment, would support work on barium titanate optical switches, high-temperature single-photon detectors, and advanced packaging.
The Palo Alto company aims to build fault-tolerant, utility-scale quantum computers using a silicon photonics architecture that leverages semiconductor manufacturing. PsiQuantum said the proposed incentives would help scale component manufacturing at U.S. facilities, including work tied to BTO wafers, chip-to-fiber coupling, and cryogenic photonic control hardware.
PsiQuantum’s U.S. supply chain work builds on its long-running manufacturing partnership with GlobalFoundries, which began in 2019, and its broader federal engagement. In 2025, PsiQuantum advanced in DARPA’s quantum benchmarking efforts and broke ground at the Illinois Quantum and Microelectronics Park in Chicago.
- Proposed federal incentives: $100 million under the CHIPS and Science Act

“PsiQuantum’s world-leading capability in photonics will help write the next chapter in the history of computing. Thanks to bold action from Washington, our company will continue to invest in manufacturing these cutting-edge components right here in the United States,” said Victor Peng, Interim Chief Executive Officer of PsiQuantum.
