Report sources: provenance register

The register of the reports and pages the portal reads for its evidence on quantum technologies in Europe and the world: who published them, which edition, how they may be used, the version that was read, and when they were last checked for a new edition. The reports are linked to their publishers; the document library keeps archive copies only where a licence allows it and of the qt.eu documents this portal succeeds. Figures from them appear on the portal only after an editor has approved them.
