Quantum computing startup Diraq has raised $15 million as part of a new funding round that’s yet to be completed.
The deep tech venture, which was spun out of the University of NSW in 2022 last month announced it had collaborated with fellow Sydney startup Emergence Quantum to develop technology that reduces the size of the circuits required to run a silicon-based quantum computer. Diraq last raised a $10.5 million in Series A2 extension in June 2024.
The new funding was revealed by Capital Brief based on ASIC filings, with existing backers Main Sequence, Uniseed, NewSouth Innovations and France’s Quantonation joined by Singapore’s ICM Global Funds, which chipped in $4.6 million, and US fund Morgan Creek Digital.
Startup Daily understands that the round is still open for additional investors.
The additional $15 million takes the total raised by Diraq past US$137 million including government funding.
Diraq was founded by Andrew Dzurak, a professor in quantum engineering at UNSW. He led the team that built the first quantum logic gate in silicon in 2015 and the new mechanisms they’ve developed are the result of more than two decades of research. They hope to release their first product by the end of the decade.
Diraq is a world leader in building quantum processors using silicon ‘quantum dot’ technology. The engineers found a new way of precisely controlling single electrons nestled in quantum dots that run logic gates.
Earlier this year, Diraq expanded its Chicago presence, set up in the Illinois Quantum and Microelectronics Park alongside the likes of PsiQuantum after landing US government contracts.
Diraq has been linking itself closely with US government science and technology initiatives in 2025.
In March, it and particle physics laboratory Fermilab were awarded the US Department of Energy Quandarum project to help search for dark matter. Then in April, they signed an early stage contract with the US Defense Advanced Research Projects Agency (DARPA) as part of its Quantum Benchmarking Initiative.
