Diraq

About

Diraq develops silicon spin-qubit quantum processors that can be fabricated with standard CMOS processes for integration into conventional data-center infrastructure.

Mission

Diraq is an Australian quantum computing company commercializing silicon spin qubits (quantum dots) manufactured on 300 mm CMOS wafers, allowing dense co-integration of quantum and classical control electronics on a single chip. Its qubits run at roughly 1 K—warmer than superconducting approaches—simplifying cryogenic requirements and enabling a server-rack-compatible form factor for hybrid quantum-classical workloads. The firm’s roadmap calls for delivering an initial quantum computer by 2029 and reaching utility-scale performance by 2033, ultimately supporting millions of qubits at a projected cost of under one dollar per qubit. In late 2025, it demonstrated >99 % two-qubit gate fidelity on randomly selected industrial devices and advanced to Stage B of DARPA’s Quantum Benchmarking Initiative. Scaling efforts are reinforced through partnerships with imec, GlobalFoundries, Nvidia, and Dell. The business has grown to more than 70 staff and PhD students across research, development, and commercialization functions in Sydney, Melbourne, Palo Alto, Boston, and Chicago. Revenue figures were not disclosed, but the company has attracted backing from Main Sequence Ventures, Quantonation, and Australian superannuation funds including Hostplus and UniSuper.
