Expert review sheet of the faceted taxonomy (every value, definition and source)
Overview
The technology atlas of Quantum networks and repeaters: its value chain, the documented actors by role, facilities, funding, patents and publications, standards and policy measures on one page, each from a source the portal already publishes. Each section says whether these sources document the technology, show an evidence gap or hold nothing about it.
| Section | State in these sources | Records |
|---|---|---|
| Value chain | No evidence found in these sources | 0 |
| Actors by role | Documented in these sources | 49 |
| Facilities and access | No evidence found in these sources | 0 |
| Funding | Documented in these sources | 7 |
| Patents and publications | Documented in these sources | 2 |
| Standards | Documented in these sources | 20 |
| Policy measures | Documented in these sources | 4 |
| Evidence gaps | No evidence found in these sources | 0 |
- Documented in these sources: at least one record of these sources is about this technology.
- Evidence gap in these sources: the parts tree names a stage, but no documented European actor is linked to it here. Evidence gap in these sources, not a finding of dependency.
- No evidence found in these sources: No evidence found in these sources. It means only that these sources hold nothing on it.
Public layer: structure and documented actors only. Actor roles come from typed, dated relationships and are never inferred from shared projects or patents. Supplier assessments of the restricted dependency map are not shown on this public page. No technology readiness level is given.

Value chain
The stages of this technology in the parts tree, a reference structure from review articles and EU law, with the European companies whose own product page names a product line for the stage or a part under it (the curated supplier directory).
No evidence found in these sources. The parts tree has no platform or part for this technology.
Actors by role
Organisations with a documented relationship to this technology: a product line on the company’s own product page, the host or programme the infrastructure catalogue names for a facility, or the operator of an access route. Each row names its source and the date it was read. Roles are never inferred from taking part in the same project or patent.
| Role | Actors | State | Where |
|---|---|---|---|
| Manufacturer or supplier of a part | 0 | No evidence found in these sources | 0 organisations in the table below. |
| Host, operator or access provider | 0 | No evidence found in these sources | 0 organisations in the table below. |
| Funder or programme | 0 | No evidence found in these sources | 0 organisations in the table below. |
| Researcher or developer | 49 | Documented in these sources | Organisations confirmed under this technology by the classification; listed in “Organisations and companies” below. Participants in EU-funded projects are counted per pillar in technology intelligence. |

Each project counts once. A total adds the amount each source states for its projects within one measure and one currency only: EU contributions, national awards and other measures are never added together. Total cost includes the award and is shown separately. A country filter keeps whole projects with a participant in the country, so its total is not the country's share. Programme envelopes, partner shares, co-funding and payments are separate layers and are never added to awards; payments are not published by the sources used. Outputs are linked only through an explicit project or grant identifier or reviewed documentary evidence, never by name alone; only a reviewed document can show a demonstrated contribution. CORDIS and Funding & Tenders amounts are one measure, the EU contribution (maximum grant agreed in the grant agreement, not payments). Country codes EL and UK are read as GR (Greece) and GB (United Kingdom). National and regional rows whose title names no quantum technology are left out unless asked for. EU and national totals are shown apart and never added.
Includes projects from the ANR open data: ANR, data.gouv.fr, ODbL 1.0; those rows are shared alike under the Open Database Licence.
10 confirmed project pages have no award record and are not in the totals.

Evidence gaps
Stages of the value chain for which these sources link no documented European actor. Evidence gap in these sources, not a finding of dependency. A company may well supply the stage without a product page the directory has read; a missing record is never proof of a strategic dependency.
No evidence found in these sources. No value chain is recorded for this technology, so no gap can be named.
