What Diraq does

Diraq is an Australian quantum computing company, spun out of the University of New South Wales (UNSW) Sydney in 2022 under Professor Andrew Dzurak, that is building utility-scale quantum computers using silicon spin qubits encoded in modified CMOS transistors. Its core technology encodes quantum information in the electron spin state of quantum dots fabricated on 300mm semiconductor wafers using industry-standard CMOS processes at imec and GlobalFoundries, with qubits operating at approximately 1 Kelvin—significantly warmer than the millikelvin temperatures required by superconducting platforms, which reduces cryogenic infrastructure cost. Published technical milestones include >99% two-qubit gate fidelity, 8-qubit coherent control on 300mm foundry-fabricated devices, one million error-corrected operations per minute, and the first mid-circuit measurements and feedforward in silicon spin qubits. The company's roadmap targets millions of qubits on a single chip by 2031 and tens of millions by 2033, at a sub-$1 per-qubit cost target enabled by leveraging existing semiconductor fabs rather than building specialized quantum foundries.

Diraq is pre-revenue and capital-intensive, with over USD 137 million raised from In-Q-Tel, Quantonation, Morgan Creek Digital, Australian superannuation funds (Hostplus, NGS Super, UniSuper), a AUD 20 million equity investment from Australia's National Reconstruction Fund Corporation, and a Letter of Intent for up to USD 38 million in US CHIPS R&D funding. Its commercial model is direct enterprise sales of full-stack quantum computing systems to government laboratories, supercomputing facilities, and commercial data centers in the US, Europe, Australia, and Japan, with the first commercial product targeted for the first half of 2029 and broader commercial sales expected around 2031. Diraq also has a secondary vertical in quantum sensing through the Fermilab-led Quandarum project.

The company's go-to-market combines a direct enterprise sales motion with an OEM/embedded channel through semiconductor ecosystem partners: GlobalFoundries (founding customer of its new Quantum Technology Solutions business unit) for fabrication, imec for 300mm CMOS process R&D, Nvidia for hybrid quantum-classical compute, and Dell for data center systems integration. Strategic government positioning includes selection for Stage B of DARPA's Quantum Benchmarking Initiative alongside IBM, Quantinuum, Atom Computing, and IonQ, tenancy at the Illinois Quantum and Microelectronics Park, and the recent appointment of former Broadcom and Philips Semiconductors (NXP) CEO Scott A. McGregor as Chairman to lead US expansion. Diraq holds 60+ filed patents and has published 40+ papers in Nature and Science family journals.

Direct peers

• Quantum Motion: UK-based quantum computing company developing silicon spin qubit processors using CMOS-compatible foundry processes. Directly comparable to Diraq in qubit modality, foundry-first manufacturing strategy, and pursuit of utility-scale fault-tolerant quantum computing.
• Silicon Quantum Computing (SQC): Australian silicon-based quantum computing company spun out of UNSW (same academic lineage as Diraq) pursuing atomically-precise silicon qubits. Closest geographic and technological peer, competing for the same Australian talent pool and government quantum funding.
• PsiQuantum: Photonic quantum computing company pursuing fault-tolerant utility-scale quantum computers and co-tenant at the Illinois Quantum and Microelectronics Park alongside Diraq. Competes for the same DARPA QBI Stage B cohort and utility-scale quantum market despite different qubit modality.
• Quantinuum: Trapped-ion quantum computing company formed by the merger of Honeywell Quantum Solutions and Cambridge Quantum. Co-tenant at the Illinois Quantum and Microelectronics Park and fellow DARPA QBI Stage B participant, competing head-to-head for utility-scale quantum commercial revenue.
• Atom Computing: Neutral-atom quantum computing company and fellow DARPA QBI Stage B participant pursuing utility-scale fault-tolerant quantum computing. Differentiates from Diraq on qubit modality but is the closest pure-play comparable in stage, funding profile, and target end-market.
• QuEra Computing: Neutral-atom quantum computing company and fellow DARPA QBI Stage B participant pursuing utility-scale fault-tolerant quantum computers. Comparable in stage, target market, and government-customer orientation, though differs on qubit modality.

Broad incumbents

• Intel (Quantum): Intel's quantum computing program (Tunnel Falls, Horse Ridge) pursues silicon spin qubits fabricated on 300mm CMOS processes, leveraging Intel's own fabs. A broad incumbent with comparable qubit modality but vastly greater manufacturing resources and a much broader semiconductor portfolio.
• IonQ: Public trapped-ion quantum computing company and IQMP tenant competing for the same enterprise and government quantum computing customers as Diraq. Functions as a broad incumbent with deeper commercial traction but a different (less scalable at the CMOS level) qubit modality.
• IBM Quantum: Superconducting quantum computing incumbent and IQMP tenant with the largest installed base of quantum systems and the deepest enterprise sales motion. Competes with Diraq for government and enterprise quantum computing budgets across US, Europe, and Asia.

Emerging players

• QuTech / Intel Delft: European quantum computing research organisation closely collaborating with Intel on silicon spin qubits. Operates from a research-and-prototype position and shares Diraq's silicon-spin-qubit modality, but lacks a productised commercial roadmap of comparable scale.
