Washington takes equity in quantum companies for $400M

US Department of Commerce — D-Wave, Rigetti, Quantinuum, PsiQuantum — D-Wave, Rigetti and Quantinuum each finalized $100M CHIPS and Science Act agreements with the Commerce Department on 8 Sep 2026, and PsiQuantum signed definitive documentation for $100M of its own. The condition attached to the first three is the notable part: the federal government takes a minority, non-controlling equity stake in each company. The stated work is manufacturing, not algorithms — D-Wave toward a 100,000-qubit annealer and a 10,000-qubit gate machine with 100 logical qubits; Rigetti on miniaturised readout electronics, a new cryostat architecture and high-connectivity fabrication; Quantinuum on 300 mm ion-trap wafers with GlobalFoundries and lasers with Monarch Quantum; PsiQuantum on optical switches, high-temperature single-photon detectors and packaging.
