PsiQuantum has signed a $125 million agreement with the U.S. Defense Advanced Research Projects Agency (DARPA) under the agency's Quantum Benchmarking Initiative. This deal is intended to determine the feasibility of building industrially useful quantum computers by 2033. The funding will support rigorous testing of PsiQuantum's hardware and software stacks, which utilize a photonics-based approach to quantum information processing. CEO Victor Peng noted that this vetting process will help the industry distinguish between theoretical potential and practical reality. PsiQuantum's first commercial-scale machine is currently projected to be operational by 2030. The company leverages silicon photonics and standard semiconductor manufacturing processes through its partnership with GlobalFoundries. This award follows a previous $31.8 million agreement with DARPA and deepens the firm's ties with the U.S. government. PsiQuantum recently raised $1 billion at a $7 billion valuation, with participation from major investors like BlackRock and Nvidia's venture arm. The company's expansion into Australia and its ongoing work in the U.S. underscore a global strategy to dominate the fault-tolerant quantum computing market.
