The project has secured €25 million in EU funding, matched by national contributions from participating Member States, bringing total funding to around €50 million.
The first phase of the programme is scheduled to begin in early 2026 and will run for three and a half years. It brings together 23 partners from eight EU countries, spanning academia, research and technology organisations, large industrial players and small and medium‑sized enterprises. The initiative is supported under the EU Chips Joint Undertaking and aligns with broader objectives of the European Chips Act and European Quantum strategy.
SUPREME’s core aim is to develop scalable, stable fabrication processes for superconducting quantum devices and make them accessible to industry and research organisations. A key technical milestone will be the fabrication and demonstration of a 3D‑integrated qubit module containing 200 qubits, intended to demonstrate improved stability, yield and reproducibility in superconducting chip manufacturing.
“This initiative has been set to strengthen the European quantum ecosystem,” said Pekka Pursula, vice president for microelectronics and quantum technology at VTT and coordinator of the SUPREME consortium. “We will make sure that the innovations developed through SUPREME can be widely adopted by businesses across Europe, ultimately delivering significant market impact.”
The project will focus on developing and validating processes such as angle‑evaporated and etched junctions, 3D integration and hybrid technologies for applications in quantum computing, sensing and communications. The consortium is targeting technology and manufacturing readiness levels of TRL 6 and MRL 6.
To support adoption, SUPREME plans to offer piloting services, shared fabrication runs and process design kits, enabling companies to design and prototype their own quantum devices while sharing development costs.
The consortium combines European expertise in superconducting technology from academia, RTO’s, industrial technology developers and end-users. The consortium involves the following 23 partners from eight EU Member States including VTT, coordinator (Finland); Delft University of Technology (Netherlands); Fraunhofer Gesellschaft für Angewandte Forschung e.V. (Germany) and The French Alternative Energies and Atomic Energy Commission – CEA (France).
Large enterprises include Infineon Technologies and IQM Finland Oy, along with a host of small and medium enterprises.
