Diraq Advances to Stage C of DARPA Quantum Benchmarking Initiative
AI-summarised brief · reviewed before publication
Diraq has moved into Stage C of DARPA’s Quantum Benchmarking Initiative, the program’s final phase that independently validates whether a quantum‑computing approach can reach utility scale by 2033. In this stage, DARPA’s verification team will examine Diraq’s silicon‑spin‑qubit design, performance metrics, manufacturing economics and the critical capabilities needed for a fault‑tolerant system. The company will receive an initial $51 million tranche to fund technical demonstrations, infrastructure upgrades and further development of its silicon‑based platform. Diraq’s approach leverages existing 300 mm CMOS processes, allowing it to aim for 150 000 qubits by 2029 and over 2 million physical qubits on a single chip by 2031—two years ahead of the QBI schedule. The advancement follows successful Stage B completion and coincides with a $38 million Letter of Intent from the U.S. Department of Commerce under the CHIPS and Science Act.
