Pentagon's conditional $150 million loan would support PsiQuantum's California prototype hub
The Office of Strategic Capital's commitment goes to a company DARPA is already evaluating in the final stage of its Quantum Benchmarking Initiative. The loan isn't guaranteed.
The Department of War's Office of Strategic Capital announced on Thursday, Oct. 8, a conditional commitment to lend PsiQuantum up to $150 million to support its 140,000-square-foot hub in Milpitas, Calif. There, the photonic quantum computing company develops and validates the prototype systems behind its fault-tolerant architecture.1–2 PsiQuantum said the financing would support its acquisition of test equipment, infrastructure for system assembly, integration and testing, and advanced cryogenic systems for its prototypes.2

PsiQuantum sits in Stage C, where government evaluators test whether a proposed utility-scale quantum computer can be built as designed and operated as intended.4 The department says the loan builds on the office's "ongoing collaboration" with the initiative.1 In July, PsiQuantum said it was one of two companies in that stage.5 Four more organizations have since joined Microsoft and PsiQuantum there: Atom Computing, Diraq, IBM and IonQ.4 The department says their advancement represents about $200 million in new funding.3
The commitment follows a $125 million expanded DARPA agreement PsiQuantum announced in July and a $100 million CHIPS and Science Act award it finalized with the Commerce Department in September.2, 6 The loan would be paired with co-investment from PsiQuantum, the company said.2 Neither announcement disclosed the loan's term, interest rate, any warrants or the size of that co-investment.1–2
Financial close is the next marker; to reach it, PsiQuantum must satisfy financial, legal, technical, due diligence and other requirements set in the commitment.1 DARPA's Stage C team, meanwhile, will be "closely scrutinizing the hardware and systems as they develop," said Micah Stoutimore, the initiative's managing director.4
