Diraq is on a mission to make quantum computers practical enough to tackle problems beyond the reach of today's machines. From new life-saving medicines and lighter materials for spacecraft, to predicting climate change and optimising logistics, quantum computers could help solve some of the most complex problems humanity faces.
Many of these breakthroughs depend on understanding how atoms and molecules interact, which quickly becomes too complex for today's computers to model accurately. However, solving problems like these will need millions of quantum bits – known as qubits – and getting there isn't just a scientific challenge, it's an industrial one. This is exactly what Diraq is engineering a solution for.
Diraq is a quantum computing company that turns transistors into qubits. Its proprietary silicon spin qubits are made the same way as the chips in today's phones and laptops, using existing semiconductor foundries rather than custom manufacturing. By building in the industry’s mature processes, Diraq can pack far more qubits onto a single chip than other quantum technologies, at a fraction of the cost.
Founder and CEO, Andrew Dzurak, invented the technology based on over 20 years of research and established Diraq to take it from the lab to commercial scale. In 2025, Diraq reported the first qubits made entirely in a commercial foundry, on standard 300mm wafers, to be accurate enough for error-corrected quantum computing, a result published in Nature.
How will quantum and AI work together?
Just as AI has been a game-changing technology, so will quantum computing. AI changed what we can do with data; quantum computing will change what we can do with matter, molecules and materials.
The future of computing isn't quantum computers replacing today's machines. It's quantum computers working alongside classical and AI systems, each doing what it does best. AI is powerful at finding patterns in huge amounts of data, but it can only learn from data that already exists. Quantum computers create new knowledge instead, using qubits to simulate physical behaviour directly rather than approximate it. Together, they could speed up discovery. A quantum computer could simulate a new drug or material, and AI could use those results to decide what to test next.
“The promise of quantum computing is extraordinary. Quantum computing could help us cure diseases we can't treat today, store clean energy more cheaply and feed more people with less damage to the planet. That promise only becomes real if quantum computers are built at scale and made accessible to the people solving those problems," said Andrew Dzurak, CEO and Founder of Diraq.
When will Diraq reach utility-scale quantum computing?
By the end of 2026, Diraq will deploy a quantum computer inside an Equinix data centre in Sydney. It will be the world's first silicon spin quantum computer to run in a shared commercial data centre. The system's chip holds eight qubits, fits alongside standard servers and draws less than 20kW of power, with scaling up needing only a chip replacement. The deployment will test how the system is monitored and operated alongside classical and AI infrastructure and give customers a place to see quantum computing in action.
Diraq's current roadmap targets utility scale by 2031, with more than two million physical qubits on a single chip. Utility scale is the point at which a quantum computer can solve problems that deliver more value than the machine costs to build and run. Diraq is one of just six companies globally that has been selected by US Defense Advanced Research Projects Agency (DARPA) to advance to the final stage of the Quantum Benchmarking Initiative, the world's most rigorous programme evaluating whether quantum computing can achieve utility-scale operation.
About Diraq
Founded in Sydney, Diraq builds silicon spin quantum computers using existing CMOS manufacturing processes. It has more than 130 team members across Australia and the United States, with sites in Sydney, Melbourne, Palo Alto, Los Angeles, Chicago and Albuquerque. Diraq works with NVIDIA, Dell Technologies, GlobalFoundries and imec, has been selected for Stage C of DARPA's Quantum Benchmarking Initiative, and has signed a US$38 million letter of intent with the US Department of Commerce under the CHIPS and Science Act.
