Technology map of European quantum projects

How the EU-funded quantum projects in CORDIS connect the building blocks they work on, the hardware platforms they use and the pillars they serve (the three application pillars plus enabling technologies and supply chain). Wider ribbons mean more projects. Select a category to see its connections and its largest projects.

628 of 1256 projects placed, in 18 categories

Select a category in the diagram, or use Tab and Enter, to see its connections and largest projects.

Method: building blocks and hardware platforms are keyword matches on project titles; the pillar is the confirmed classification of the project, as counted on the technology hubs (an editor decision or a high-precision taxonomy rule); a project without one is drawn under “No confirmed pillar”, never under a default pillar. Projects whose title names neither a building block nor a platform are not shown. A project that names several categories in a column is split evenly between them, so each column adds up to the same total; the counts are whole projects. Source: CORDIS, Publications Office of the European Union (Horizon 2020 and Horizon Europe only; quantum projects of other EU programmes, such as Digital Europe, are counted on the funding trends page, not here).

Patents, actors and a dated brief for one technology: the technology intelligence pages bring the sources of this map together per technology.

Explore every technology on the technology hub One page per pillar and technology family, with the parts of its platform.
