Australia’s Quantum Companies and the State as a Shareholder Bet

Dr. Kris Naudts, Zeynep Koruturk and Donald Harmitt @ Firgun Ventures.

Firgun Ventures is a VC firm investing in Series A/B quantum scale-ups globally.

For a quarter of a century Australia's quantum reputation rested on world-leading research talent, exemplified by figures such as Michelle Simmons, the 2018 Australian of the Year, and CEO of Firgun Ventures’ portfolio quantum computing company Silicon Quantum Computing. The country is now attempting something deep tech usually finds difficult, converting that scientific strength into large-scale commercialisation. Australia no longer wants to produce excellent physics alone; it wants companies, supply chains and exportable capability, and is prepared to put public capital directly behind that goal. What makes the Australian quantum companies an interesting case study is less the scale of the spending than its unusual shape, because the government is increasingly acting not as a grant-maker but as a direct equity investor.

The Scale and Shape of the National Bet

The ambition was formalised in the 2023 National Quantum Strategy, which set the goal of making Australia a global quantum leader by 2030, and the figures behind it are substantial. More than A$1.6 billion in sustained public investment has given the country the world's fifth largest quantum workforce, more than 40 companies across sensing, communications and computing, and 26 specialised research institutions. What distinguishes the approach is its breadth and its mechanism. Rather than backing a single technological pathway, Australia is cultivating domain breadth across the stack, and instead of solely funding research and stepping back, the state is taking shares in the companies it supports.

Australia's Deliberate Bet on Manufacturing Economics

The logic is clearest in quantum computing, where Australia's two leading homegrown contenders, Silicon Quantum Computing and Diraq, are both pursuing silicon-spin qubits built with standard semiconductor processes. This is an asymmetric bet that the qubit race will be won not on headline qubit counts but on manufacturing economics, where the semiconductor industry's accumulated trillions in research and development become an advantage other modalities cannot easily contest. 

Diraq, founded in Sydney, is developing utility-scale machines compatible with existing chip fabrication, and in February 2026 the company secured an A$20 million (US$14 million) equity investment from Australia's National Reconstruction Fund Corporation (NRFC), the A$15 billion vehicle established to rebuild Australian industrial capability. The signal strengthened in May 2026, when Diraq signed a letter of intent for up to $38 million from the US Department of Commerce under the CHIPS programme. That an Australian firm should draw on US industrial funding at the very moment Washington is placing its own large quantum bet is a notable outcome for the ecosystem. Meanwhile, Silicon Quantum Computing is advancing commercial-scale processors with its proprietary PAQMan process, backed by a A$20 million NRFC investment of its own.

The most intriguing case, and the one that invites the sharpest scrutiny, is PsiQuantum, a US company headquartered in Palo Alto and founded by expatriate Australian physicists whose photonic approach traces back to the University of Queensland. Its billion-dollar project near Brisbane Airport, intended to house the world's first utility-scale quantum computer, is backed by roughly A$940 million from the Australian and Queensland governments through a mix of equity, grants and loans. This is sovereign-capability building staked on a foreign-headquartered firm, and it raises the fair question that diversified state investment cannot avoid, namely whether the returns, financial and strategic, will justify the somewhat uncommon arrangement.

A Sensing Bet That Is Already Paying Off

If computing is the longer commercial play, sensing is where Australia is already generating momentum, and it is here that the breadth of the national bet earns its keep. Q-CTRL is the standout, delivering AI-powered software that accelerates platforms such as IBM Quantum, and it raised one of the world's largest quantum Series B rounds to date at $113 million. In 2025 DARPA awarded Q-CTRL contracts under the Robust Quantum Sensors programme with Lockheed Martin as a subcontractor, and Q-CTRL's Ironstone Opal system has outperformed a high-end inertial navigation platform in flight, reaching up to 111 times greater positioning accuracy when GPS was unavailable, validated aboard a Royal Australian Navy vessel.

The ecosystem extends well beyond a single name. In Sydney, DeteQt is commercialising diamond-on-chip magnetometers for GPS-denied environments; in Adelaide, QuantX Labs has flown TEMPO, a next-generation optical atomic clock now in orbit aboard a SpaceX rideshare; and Quantum Brilliance is building room-temperature diamond chips and magnetic sensing products. Together these firms show that the sensing bet rides not on one technology or one company, but on a spread of near-term capabilities already finding defence and commercial customers.

When the State Becomes a Shareholder

The thread connecting the large majority of these companies is a sovereign financing model that is reshaping how Australia funds its quantum industry. The National Reconstruction Fund Corporation has become the government's primary instrument for taking equity in quantum startups, and beyond Diraq and SQC it has backed Quantum Brilliance to build Australia's first diamond-based quantum foundry and QuintessenceLabs to advance quantum-resilient cybersecurity. When a state moves from awarding grants to holding shares, it signals a different order of conviction, underwriting an industry while accepting downside exposure in exchange for sovereign capability. Grants reward good science regardless of commercial outcome, while equity ties the taxpayer's return directly to the company's success.

What Australia's Model Means for Investors

For investors weighing where quantum value will accrue outside the United States, Australia is running the most revealing policy experiment of the moment, and its lesson differs from Canada's, covered in our “Four Quantum Unicorns, One Country” article featured on the Quantum Insider. Where Canada has tried to retain its champions through headquarters clauses, Australia is binding the state to company outcomes through the cap table itself, a more aggressive and more telling stance. The silicon-spin thesis shared by SQC and Diraq is one of the most interesting observations worth understanding, because it wagers that the eventual winners in quantum hardware will be those that can manufacture at semiconductor scale rather than those posting the highest near-term qubit counts. For a venture investor that is an attractive shape of bet, rewarding process maturity and capital discipline over headline physics. The signal for European and British quantum is pointed, and it cuts against the grain of how much of the continent still funds the field. Australia has shown that a mid-sized economy can compete credibly at the frontier by combining domain breadth, sovereign equity and deep alliances, yet ecosystems still relying on grants alone are now competing against states willing to sit on the cap table, a higher bar than most European quantum strategies have set themselves.

What to Watch Over the Next One to Three Years

Australia's final structural advantage is that it is not building alone, coordinating interoperable defence technology with the United Kingdom and the United States under Pillar 2 of AUKUS, where quantum is a named priority, and signalling plans to co-invest with venture firms in a defence and dual-use fund of up to A$1 billion. The binding constraint, as everywhere, is talent, and with CSIRO projecting 19,400 quantum jobs in a A$6 billion domestic industry by 2045, a deep pipeline of skilled people may prove the most durable advantage of all. What Australia is ultimately testing is a thesis as much about capital structure as about physics. The country has decided that diversification across the stack, with the state acting as an active shareholder rather than a passive funder, is the surest route from world-class research to commercial scale, and whether it holds will be settled by whether public equity can stay patient long enough for an industry to mature.
