About
Diraq is an Australian quantum computing company building silicon spin qubit processors using CMOS semiconductor fabrication. It spun out of UNSW Sydney in 2022 and is based in Sydney, with offices in the US and Singapore. Diraq has raised more than 135 million dollars in total, including 20 million dollars from Australia's NRFC in February 2026, and it partners with GlobalFoundries for volume manufacturing. The company demonstrated 99.9% control accuracy on imec-fabricated CMOS qubits. Its roadmap targets 100 to 200 qubit systems for research partners by 2026 and a first commercial product, with thousands of physical qubits, in the first half of 2029. Diraq is a confirmed DARPA QBI participant and has signed a letter of intent to join Illinois Quantum Park, integrating with the US quantum computing ecosystem. In October 2025, Diraq and NVIDIA demonstrated a low-latency hybrid classical-quantum link via NVQLink, enabling one million fault-tolerant operations in under a minute. In 2025, Diraq published a hot qubits result of 99.85% single-qubit fidelity and 98.92% two-qubit fidelity at 1 Kelvin, a 10x higher operating temperature than conventional superconducting systems, which reduces cooling costs. High-fidelity qubits, above 99% across all metrics, were demonstrated on 300mm wafers at GlobalFoundries and IMEC, confirming industrial CMOS compatibility at volume-manufacturing scale. In May 2026, Diraq reported progress on scaling qubit count by increasing on-chip density, the central engineering thread for its 2029 commercial target. Update 2026-06-17: Diraq is expanding its U.S. operations by doubling its Palo Alto team to advance its silicon-based quantum computing approach.
