Governments have supported quantum computing research for decades, but the relationship is beginning to change. New US investments in quantum companies, manufacturing and supply chains show public funding moving beyond scientific research towards industrial capacity and, in some cases, direct economic participation. As quantum computing becomes a strategic technology, governments increasingly appear willing to help finance the industry required to deliver it.

Governments have always been important to quantum computing. Universities, national laboratories and research programmes provided much of the funding that allowed quantum technologies to develop long before there was a credible commercial market for them. Even as private investment increased, public money continued supporting research, infrastructure and national quantum programmes.

What is happening now is different.

During September, the US Department of Commerce finalised a series of CHIPS and Science Act awards targeting not simply quantum research, but the manufacturing technologies and supply chains required to build quantum computers at scale. D-Wave, Rigetti, Quantinuum and PsiQuantum were each awarded up to $100 million, while GlobalFoundries received an award of up to $375 million focused on quantum semiconductor manufacturing. On 16 September, the government went considerably further, finalising an award of up to $1 billion for Anderon, the newly formed IBM subsidiary intended to create a US-based pure-play quantum foundry.

The scale is important, but so is the structure. In some of these agreements, the US government is not behaving solely as a provider of research grants. D-Wave’s definitive agreement, for example, gives the Department of Commerce a minority, non-controlling equity position as a condition of receiving the funding. The government is therefore acquiring an economic interest alongside its strategic interest in developing domestic quantum capability.

Quantum computing is beginning to move from research policy towards industrial policy, and governments are starting to finance that transition accordingly.

From funding science to building an industry

Public investment in emerging technologies is hardly unusual. Semiconductor manufacturing, aerospace, energy, telecommunications and defence have all developed through complex relationships between governments and private companies, particularly when the technologies involved require enormous capital investment or have strategic national importance.

Quantum computing increasingly fits both descriptions.

Building useful fault-tolerant quantum systems requires sustained investment in processors, fabrication, packaging, control electronics, photonics, cryogenics and other specialist technologies. Many of those capabilities have to be developed years before quantum computing can generate commercial revenues comparable with the investment required to create them.

That produces a financing problem. Private investors are being asked to fund expensive industrial infrastructure while the size and timing of the eventual market remain uncertain. Governments, however, can evaluate the return differently because economic profit is only one part of the calculation.

Domestic manufacturing capacity, technological sovereignty, national security, scientific leadership, specialist employment and control over strategic supply chains can all represent returns on public investment even before a quantum company produces conventional commercial returns.

The September awards make that distinction particularly clear. The Department of Commerce describes its quantum investments in terms of semiconductor processes, manufacturing bottlenecks, packaging, materials and supply chains rather than simply improvements in qubit performance. The objective is increasingly to establish the industrial capabilities needed to manufacture quantum systems inside the United States.

Manufacturing has become the target

The individual awards reveal how specific this strategy has become.

Quantinuum’s $100 million award addresses manufacturing bottlenecks associated with scaling trapped-ion quantum computers, including integrated photonics, specialised semiconductors for cryogenic operation and reliable optical components. The company is working with GlobalFoundries on next-generation ion traps and control electronics and with Monarch Quantum on lasers and optical components.

PsiQuantum’s award focuses on semiconductor manufacturing technologies needed for photonic quantum computing, including electro-optic materials, single-photon detectors and photonic packaging. D-Wave’s funding targets semiconductor process technologies for superconducting annealing and gate-model systems, including materials, interfaces and advanced packaging.

GlobalFoundries occupies another part of the emerging structure. Its award of up to $375 million is intended to develop a domestic quantum foundry capable of supporting multiple quantum architectures and moving technologies from laboratory development towards manufacturing.

And then there is Anderon. The newly created IBM subsidiary has received an award of up to $1 billion to establish a pure-play quantum foundry, with IBM committing an additional $1 billion. The ambition is significant because a foundry model assumes something larger than an individual quantum computer. It assumes the emergence of a supply chain in which quantum technologies can increasingly be designed, fabricated and manufactured through industrial processes.

Taken together, these investments suggest that government policy is beginning to anticipate the infrastructure of a future quantum industry rather than waiting for that industry to appear by itself.

The state can afford a different investment horizon

This matters because the economics of quantum computing remain difficult.

Commercial activity is growing, but the revenues generated by quantum computing are still small relative to the capital required to develop fault-tolerant systems and the manufacturing infrastructure around them. For private investors, that creates a familiar problem: the technology may eventually become extremely valuable while still proving difficult to finance through the years required to reach that point.

Governments operate on a different investment horizon. A national quantum capability may have strategic value even if its direct financial return is initially poor, particularly if policymakers believe future computing infrastructure will affect defence, cryptography, materials science, pharmaceuticals, energy or industrial competitiveness.

The calculation becomes similar to other forms of strategic infrastructure. Governments do not necessarily invest in semiconductor fabrication, energy networks or defence capabilities because each individual investment produces the highest available financial return. They invest because allowing critical capacity to exist entirely elsewhere can create economic and strategic dependencies.

Quantum computing is increasingly being treated in the same way.

That helps explain why manufacturing and supply chains have become central to public investment. A country can possess excellent quantum researchers and still remain dependent on foreign fabrication, packaging, optical components or specialist materials. Scientific leadership does not automatically create industrial sovereignty.

The current US strategy is increasingly aimed at connecting the two.

When government becomes a shareholder

The equity component adds another dimension.

Under D-Wave’s agreement, the Department of Commerce receives a minority, non-controlling equity stake as part of the funding arrangement. That does not turn D-Wave into a state-controlled company, but it does alter the traditional relationship between government and technology provider. Rather than simply providing public money and hoping that the resulting technology produces wider economic benefits, the state also receives an economic interest in the company receiving support.

The approach raises interesting questions about how governments should participate in strategically important emerging technologies. If taxpayers are absorbing part of the risk involved in financing expensive technology development, there is an argument that they should also participate in some of the potential upside. At the same time, direct government ownership introduces questions about competition, technology selection and whether public policy risks favouring particular companies or architectures before the market has determined which approaches will succeed.

Those questions are particularly important in quantum computing because technological convergence has not yet occurred. Superconducting systems, trapped ions, photonics, neutral atoms and semiconductor approaches are still competing, and it remains unclear which architectures will ultimately prove capable of delivering commercially useful fault-tolerant systems.

The current US awards spread support across several approaches rather than placing a single technological bet. That reduces some of the risk, but it also demonstrates how closely industrial strategy and technology strategy are beginning to intersect.

Quantum is becoming a sovereignty question

The shift is not confined to the United States. Europe has been building publicly supported quantum infrastructure through national programmes, the Quantum Flagship and EuroHPC, which is integrating quantum computers with European supercomputing centres. Governments around the world increasingly view quantum capability through the same strategic lens already applied to semiconductors, artificial intelligence and critical digital infrastructure.

The reason is straightforward. If quantum computing eventually becomes an important part of scientific and industrial computing, countries without access to the underlying technology may find themselves dependent on infrastructure controlled elsewhere.

That dependency could extend well beyond the quantum processor itself. Manufacturing, control electronics, photonics, cryogenics, specialist materials, software and access to high-performance computing environments all form part of the emerging stack.

The strategic objective therefore becomes larger than building a national quantum computer. It is about ensuring that sufficient parts of the ecosystem exist domestically, or within trusted partner countries, to maintain access to the technology as it develops.

This is where quantum investment begins to intersect directly with the wider digital trust economy. Control over critical computing infrastructure increasingly determines who can operate it, who can access it and who remains dependent on technology developed elsewhere.

Who pays for quantum?

The quantum industry still needs private capital. Venture investors, public markets, established technology companies and enterprise customers will all be essential if quantum computing is to become commercially sustainable. Government funding cannot indefinitely substitute for a viable market.

But it can change the route towards one.

Last week, we asked who would pay for quantum computing while meaningful commercial returns remain uncertain. The September funding decisions provide part of the answer. Governments appear increasingly prepared to finance the industrial capacity required to keep the technology moving towards commercial maturity, particularly where that investment also supports domestic manufacturing and strategic independence.

That does not solve quantum computing’s ROI problem. Eventually, quantum systems will still have to deliver enough economic value to justify the infrastructure being built around them. Public investment can extend the runway, strengthen supply chains and reduce some of the financial risk, but it cannot manufacture useful applications or sustainable demand.

What it can do is ensure that potentially important technologies are not abandoned simply because the commercial market develops more slowly than the science.

The significance of the current investment wave is therefore not simply that quantum companies are receiving more government money. It is that governments are beginning to treat quantum computing as an industrial capability worth building before the commercial case has been fully proven.

Quantum computing spent decades asking governments to fund the science. The emerging industry is now asking them to help fund the factories, supply chains and companies that could turn that science into infrastructure.

Increasingly, governments appear willing to do exactly that.
