Australia’s quantum computing research is genuinely world-class. The question isn’t whether Australian scientists can build quantum computers. It’s whether Australia can capture the commercial value of that research or whether, once again, our best technology will be commercialised overseas.

The stakes are substantial. The CSIRO has estimated that quantum computing could generate $2.5 billion in annual revenue for the Australian economy by 2040. That’s a big number built on a lot of assumptions, but even a fraction of it would represent a significant new technology sector.

The Research Landscape

Australia’s quantum computing research is concentrated in a handful of institutions, each pursuing different technical approaches.

Silicon Quantum Computing (SQC) in Sydney, spun out of UNSW, is building quantum processors using individual phosphorus atoms embedded in silicon. This approach has a potential manufacturing advantage—it’s built on the same silicon technology that underpins the conventional semiconductor industry. SQC demonstrated a six-qubit quantum processor in 2025, and their roadmap targets a useful quantum computer by the early 2030s.

The University of Sydney’s Nano Institute is pursuing photonic quantum computing, using particles of light rather than atoms as qubits. Photonic approaches have interesting advantages for networking and room-temperature operation, though they face their own scaling challenges.

The Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) brings together researchers from multiple universities and focuses on both silicon and optical quantum systems. It’s been a critical funding vehicle for fundamental research.

PsiQuantum, the US-based company founded by University of Bristol and Australian researchers, has received significant Australian government support (reportedly over $900 million in combined federal and state funding) for its plan to build a commercially relevant fault-tolerant quantum computer using photonic technology in partnership with GlobalFoundries.

The Funding Picture

Government funding for quantum research in Australia has been substantial by any measure.

The PsiQuantum investment represents the single largest government commitment to quantum computing globally. It’s a bold bet—the company is pre-revenue and the technology is unproven at commercial scale. But the rationale is that quantum computing is a winner-takes-most technology, and being late means being irrelevant.

The National Quantum Strategy, released in 2023, outlined a whole-of-government approach to growing Australia’s quantum industry. It includes investment in research, workforce development, and international partnerships.

State governments are also investing. New South Wales has positioned Sydney as a quantum technology hub, with dedicated precinct development and co-investment alongside university research programs. Queensland has attracted PsiQuantum’s manufacturing operations.

Private investment has been more cautious. Australian venture capital funds have limited experience evaluating deep tech with decade-long commercialisation timelines. Most quantum investment in Australian companies has come from government grants, corporate partnerships, and international investors.

The Commercialisation Challenge

This is where things get complicated. Australia has a long and somewhat painful history of producing world-class research that’s commercialised elsewhere. Wi-Fi was invented at CSIRO. Cochlear implants were developed at the University of Melbourne. Both became significant global industries, but most of the commercial value was captured by companies outside Australia (though Cochlear Limited is a notable exception).

Quantum computing faces the same risk, amplified by several factors.

Timelines are long. A commercially useful, fault-tolerant quantum computer is probably a decade away. The research needs sustained funding over that entire period. Political and budgetary cycles are much shorter. A change in government or a fiscal tightening could reduce funding precisely when it’s most needed.

The talent pool is small. Australia produces perhaps 50-100 PhD graduates per year with quantum-relevant skills. The US, China, and Europe are actively recruiting from that pool with compelling offers. Retaining quantum talent in Australia requires competitive compensation, world-class facilities, and a credible path from research to industry.

The gap between lab and market is wide. Building a quantum processor in a university lab is fundamentally different from manufacturing quantum computers at scale. The engineering challenges—cryogenic systems, error correction, control electronics, software stacks—require capabilities that don’t exist in Australian industry today.

The customer base isn’t obvious. Who will buy quantum computers in Australia? Financial services, logistics, pharmaceutical companies, and defence organisations are the most commonly cited potential customers. But their actual demand for quantum computing, as opposed to their theoretical interest, is unproven.

What Needs to Happen

For Australia to capture meaningful value from its quantum research, several things need to align.

Sustained, patient funding. Quantum computing requires the kind of long-horizon investment that governments do better than private markets. The PsiQuantum commitment is a good signal, but it needs to be accompanied by continued funding for the broader research ecosystem, not just a single company.

Industry development alongside research. Quantum computing will need an ecosystem of supporting companies—cryogenics, control systems, software, applications development. Building that ecosystem in Australia while the core technology matures is critical.

International collaboration without dependency. Australia can’t build a quantum industry in isolation. Partnerships with US, European, and Asian research groups and companies are essential. But the terms of those partnerships matter—Australia should be contributing partners, not just suppliers of talent and research that others commercialise.

Realistic expectations. Quantum computing won’t solve useful business problems next year. Or probably the year after that. The hype cycle has been through several peaks and troughs already. What’s needed is sustained commitment based on a realistic assessment of timelines, not enthusiasm that evaporates when the first deadline slips.

Australia has a genuine advantage in quantum computing research. That advantage isn’t permanent, and it won’t automatically translate into economic value. Converting research excellence into a commercial quantum industry is a different kind of challenge—one that requires sustained investment, strategic patience, and institutional support that doesn’t waver when the excitement fades.

Whether Australia has the collective discipline to see this through is the real question.
