About
PsiQuantum is building the first utility-scale fault-tolerant quantum computer using photonic qubits manufactured in standard silicon fabs. It is based in Palo Alto, California, and uses GlobalFoundries for photonic chip manufacturing, targeting millions of qubits at scale. Victor Peng, the former Xilinx CEO and AMD President, became Interim CEO on February 10, 2026, with co-founder Jeremy O'Brien moving to Executive Chairman. PsiQuantum has raised more than $3B in total, including a $1B Series E at a $7B valuation in 2025. It partnered with the Australian government for a A$620M facility in Brisbane and is developing a US site in Chicago. Its Asia-Pacific headquarters in Brisbane expanded in 2025 with a new Test and Characterization lab at Griffith University, and Linde Engineering was contracted to deliver the cryogenic plant for the utility-scale quantum computer in Queensland, targeting operational deployment by the end of 2027. The company broke ground on the largest quantum computing facility in the Americas in Chicago, Illinois, and advanced to DARPA QBI Stage C, the most advanced stage. In September 2025, PsiQuantum launched Construct, a software platform for fault-tolerant quantum algorithm design that maps algorithms onto surface-code error correction and routes qubits across photonic chips using an Active Volume Architecture, reducing factoring operational costs roughly 50-fold compared with conventional approaches. The Omega chipset, fabricated on 200mm silicon-on-insulator wafers by GlobalFoundries, is designed to scale to million-qubit processors. PsiQuantum secured a $10.8M AFRL contract, a partnership with the National Cancer Center Japan for cancer treatment algorithm research, and collaborations with Airbus and Lockheed Martin for application-specific quantum solutions. On 21 May 2026, PsiQuantum signed a non-binding $100 million letter of intent with the US Department of Commerce under the CHIPS and Science Act, targeting domestic manufacturab
