Documented European use cases of quantum technologies, and official public services that support organisations which want to try them. Each record links to the official pages it is based on.
Documented use cases and public support services compiled from official EU and national pages and from the organisations' own press releases and technical publications, on the dates shown. Summaries are the portal's own wording of what each source reports; the portal has not checked the reported outcomes, and the organisations named have not confirmed these records. No advice is given here; contact the provider directly. Owner-reviewed for demonstration, 28 October 2026. Compiled 2026-10-21.
Demand map: who buys or trials quantum, by sector and country, from tenders, EU projects and these use cases.
Maturity as the source describes it: research (laboratory, simulation or algorithm work), demonstration (a proof of concept shown in a test or field setting), pilot (trial in operation with end users) or deployed (in regular or production use). Where a source is unclear, the weaker stage is shown, next to the words the source itself uses.
