European ecosystems highlight research, gear up for industrialization

Part 1 of a three-part series on quantum tech hubs in the EU and U.K.

This article focuses on a sampling of 18 European quantum ecosystems to track their development and composition. The infographic below maps the ecosystems and provides basic information on each.

Most of the ecosystems studied were founded since 2019, but several of them emerged from older predecessor initiatives and organizations. Oxford University’s Oxford Quantum Institute, for example, is a recent arrival that follows the Centre for Quantum Computation, launched in 1998. And the Paris Centre for Quantum Technologies (PCQT) debuted in 2022, succeeding the Paris Centre for Quantum Computing, which was established in 2014.

Universities, research institutions and high-performance computing centers are among the organizations that anchor quantum ecosystems. Those core groups typically partner with technology providers, end-user organizations, government agencies and investors.

Ecosystems operating in metropolitan areas may work together through informal networks and as hubs within national quantum ecosystems.

Key ecosystem characteristics

Europe’s history in physics research provides a solid background for its current quantum technology aims. A March 2026 analysis published by the International Institute for Strategic Studies (IISS) cited “world-class research capacity” as a part of the European Union and European governments’ distinct position in the quantum competition. IISS is a global think tank that focuses on defense and security issues.

Drilling down to quantum technologies, the EU has a 26% global share of research activity, as measured by research publications, according to Elsevier’s 2025 report, “EU as a science innovator.” That compares with a 30% share for China and 18% for the U.S., according to the Elsevier, an academic publisher based in Amsterdam.

The report noted that EU partners, the United Kingdom and Japan, each have a 5.5% slice of quantum research. That addition “demonstrates that international cooperation could play a decisive role in shaping the future of quantum technology,” the report stated.

Against that backdrop, universities are often at the center of quantum ecosystems. Examples include Bristol, Cambridge and Oxford universities in the U.K. and Sorbonne Université, Université Grenoble Alpes and Université PSL in France. Similarly, Budapest University of Technology and Economics and Eötvös Loránd University are among the core partners of Hungary’s Quantum Information National Laboratory.

Outside of academic circles, research institutes and research and technology organizations (RTOs) also heavily contribute to ecosystems. Max Planck Institutes are key partners within German ecosystems, including the Center for Integrated Quantum Science and Technology in Baden-Württemberg and the Munich Center for Quantum Science and Technology. French research institutions CNRS and Inria are part PCQT.

RTOs active with ecosystems include VTT, which co-founded InstituteQ in Finland, and TNO, which co-founded QuTech in the Netherlands.

Research institutes often provide basic research within a given field, while RTOs collaborate with industry to apply research. Research roles can overlap, however.

Commercialization challenges

IISS cites Europe’s “comparatively limited industrial scale in enabling technologies” as the downside of its position in the global quantum market.

“As quantum systems move closer to deployment, the central challenge for European policymakers lies in translating scientific leadership into resilient and scalable infrastructure,” the think tank noted.

The European Commission’s Quantum Europe Strategy, published in 2025, described the issue as getting quantum “from the lab to the fab.” That is, “further investing in building state-of-the-art quantum computing, communication and sensing infrastructures, quantum hardware and relevant enabling technologies…,” the commission stated.

That report also pointed to the need for pilot lines and design tools to back industrialization and ecosystem development.

As a follow-up to the strategy, the pending Quantum Act aims to make Europe a global leader in quantum technology, while also addressing economic, ethical and security considerations. The European Commission’s timeline for the act, as of April 2026, sets the second quarter of 2026 as the window for a proposal and targets the third quarter of 2027 for an agreement.

Some industry executives, however, express concern that the Quantum Act, if overly restrictive, could hinder innovation.

Industry partnerships

In the meantime, quantum technology companies have already emerged from university research teams and incubators. Oxford’s Department of Physics spinouts include ORCA Computing, Oxford Ionics (acquired by IonQ in 2025) and Oxford Quantum Circuits. Other examples include Quobly, a silicon spin qubit company that emerged from the collaboration of CNRS and CEA. The latter is a French research organization focused on atomic and alternative energy. In photonics, PsiQuantum leveraged research from the University of Bristol’s Quantum Technology Laboratories when developing its technology.

Such industry partnerships continue as part of ecosystems’ commercialization strategies. The IonQ Quantum Innovation Centre, announced earlier this year, will operate in Cambridge University’s Ray Dolby Centre. The university and the technology provider plan to deploy a 256-qubit system and provide access to IonQ’s quantum cloud.

Another example: the Barcelona Supercomputing Center (BSC) in 2025 announced a joint venture of Spanish companies, Qilimanjaro and GMV, would build a superconducting-qubit quantum computer for the center. The move “reinforces European technological autonomy,” according to BSC.

Business communities within quantum ecosystems will become increasingly important amid national and EU efforts to push quantum from research to commercial adoption. Developments to watch here include access to capital, attempts to improve coordination among disparate initiatives and the impact of the Quantum Act, as it takes shape.

Up next: Part 2 will cover efforts to coordinate national ecosystems in Europe and the U.K. and examine international relationships. In the meantime, click here to compare the structure of North American quantum ecosystems.
