Insider Brief

  • Diraq expansion of its investment round, bringing the total raise to USD $22 million.
  • The company attracted further investment from a number of prominent strategic investors.
  • Diraq recently announced record control accuracy of 99.9% for a quantum bit (qubit) manufactured by imec.

PRESS RELEASE — Diraq, a global leader in quantum computing based on silicon quantum dots, announced an additional $7 million USD in Series A funding. This expansion of its investment round brings the total raise to $22 million (US).

The company attracted further investment from a number of prominent strategic investors comprising deep tech venture fund Main Sequence, leading global real asset technology investor – Taronga Ventures, Uniseed and UniSuper, Co:Act Capital and additional participation from foundation shareholder and research partner, UNSW, Sydney. Diraq’s Series A2 round was led by global quantum technology specialist fund Quantonation.
Andrew Dzurak, CEO and Founder of Diraq said “Diraq welcomes our new investors, and we look forward to partnering with them as we achieve the major milestones on our road map to deliver the world’s first fault-tolerant quantum computer.”
Diraq recently announced record control accuracy of 99.9% for a quantum bit (qubit) manufactured by imec using industry-standard CMOS materials on a 300mm silicon wafer. This is a significant proof point solidifying the viability of Diraq’s technology to be manufactured at scale in a commercial environment.
The company also recently published breakthrough research in the journal Nature demonstrating high-accuracy spin-based quantum computation at warmer temperatures, overcoming a critical hurdle toward delivering silicon-based quantum processors with millions of qubits.
“Diraq’s breakthroughs are a testament to Australia’s leading position globally in quantum computing,” said Bill Bartee, Managing Partner at Main Sequence. “Their world-class team, patent portfolio, and unique approach should advance the field by bringing scalable, spin-based quantum computers into the real world. We see their potential for scaling up and their compatibility with advanced semiconductor manufacturing technology as an advantage.”
“Major technology advancements like Diraq’s quantum computers will significantly impact the real asset sector, representing a step change toward the next generation of data infrastructure. More broadly, high-performance computing capabilities will elevate critical areas such as energy modelling, climate, health, and much more. We’re pleased to support companies like Diraq that have the potential to transform both real assets, and the foundational industries they support,” added Avi Naidu, Co-Founder and Managing Partner at Taronga Ventures.
“Uniseed is delighted to partner with Diraq, who have strategically translated university developed IP into a significant commercial enterprise” said Paul Butler, Investment Director – Technology at Uniseed. “At Uniseed, we’re committed to fostering innovation that not only delivers strong financial returns but also propels the economy forward.”
“We’re proud to participate in supporting Australian deep-tech startups to commercialise their IP with home-grown talent,” said Kate Eriksson, Partner at Co:Act Capital. “As Diraq expands globally, CoAct is committed to supporting their technological advancements on the international stage.”
