Quantum technology is no longer just a research topic. It has become a matter of national strategy, discussed alongside semiconductors and artificial intelligence as a field where falling behind might cost a country its security or its share of future industries. Understanding the politics helps explain both the flood of money and some of the hype.
Why governments care
Three reasons stand out. A large quantum computer could read other nations' encrypted secrets, including archives harvested years earlier. Quantum sensors could improve navigation, surveillance and the detection of hidden objects. And if quantum computers do transform chemistry and materials, the countries that build them could gain large economic advantages. All three reasons are partly speculative, which makes planning hard: governments must invest under deep uncertainty about timing.
The United States
The National Quantum Initiative Act, signed in December 2018, launched a coordinated US federal program for quantum research, authorizing about 1.2 billion dollars over five years across several agencies and creating research centers. The CHIPS and Science Act of 2022 added further support. The defense research agency DARPA runs a Quantum Benchmarking Initiative to test which companies' plans for useful machines are realistic. Much American strength lies in private companies such as Google, IBM, Microsoft and Amazon, and in a large startup sector.
China
China made quantum science a national priority in its five-year plans and built a major national laboratory in Hefei. Its teams, many led by the physicist Pan Jianwei, launched the Micius satellite and reported quantum advantage experiments with photons (the Jiuzhang machines, from 2020) and with superconducting chips (Zuchongzhi). Estimates of China's public spending on quantum technology vary widely and are hard to verify, because much of it is not published in detail. A figure of about 15 billion dollars is often repeated, but its source is unclear. China is widely seen as a leader in quantum communication, including satellite and long-distance fiber links, while American companies are generally seen as ahead in computing.
Europe and beyond
The European Union launched its Quantum Flagship in 2018, planned at about one billion euros over ten years. The United Kingdom started a national program in 2014 and in 2023 announced a strategy of 2.5 billion pounds over ten years. Germany, France and the Netherlands run large national efforts of their own. India approved a National Quantum Mission in 2023 worth about 6,000 crore rupees, roughly 700 million dollars. Japan, South Korea, Canada and Australia all have programs, and Australia and the state of Queensland agreed in 2024 to invest close to a billion Australian dollars in PsiQuantum.
Private money and the risk of a bubble
Venture capital has poured billions of dollars into quantum startups. Investors have put billions into quantum companies, and share prices of some rose sharply in 2024 and 2025 despite modest revenues. Optimists say this is how ambitious technologies get funded. Skeptics recall the "AI winters" of past decades, when inflated promises led to collapses in funding, and warn that a quantum winter could follow if useful machines arrive later than investors hope.
Export controls and openness
Quantum physics grew through open international collaboration, with results published for anyone to read. That is changing. In 2024 the United States and several allies tightened export controls on some quantum computers, components and know-how. Supporters say that technology useful for codebreaking and military sensing should not be handed to rivals. Critics warn that framing quantum research as an arms race can feed hype and secrecy and weaken the open collaboration that science depends on.
A century of quantum
The United Nations named 2025 the International Year of Quantum Science and Technology, marking a century since the birth of modern quantum mechanics in Werner Heisenberg's 1925 work. The celebration was a reminder that today's competition rests on a shared scientific inheritance built by people from many nations; QUAN 102 tells that story.
Worked example: a small country's strategy
Imagine a country of ten million people with good universities but a modest budget. Its ministers hear that great powers are spending billions and ask whether they should build a national quantum computer. Thinking it through helps. Competing head-on in hardware would cost more than the whole science budget and might back the losing technology. Several cheaper steps carry less risk. The first is protecting the country's own data by migrating government and banking systems to post-quantum cryptography, since harvested secrets are the most concrete threat. The second is training people, because every path, from software to sensing, needs skilled workers. The third is choosing a niche, perhaps quantum sensing for its mining and water industries, where local needs and expertise meet. The fourth is joining international partnerships so researchers can use machines abroad through the cloud. This is roughly the path several smaller countries have taken. It shows that a quantum strategy need not mean winning a race; it can mean being secure, skilled and ready to use whatever arrives.
