Pilot fabrication on superconducting, photonics, semiconducting and diamond platforms
Location
EU-wide
Host
Coordinated by VTT; 21 partners from 9 European countries (organisation profile)
Programme
Horizon Europe (grant agreement 101113983), 2023 to 30 September 2026
Status
Project period ended, per the source. Horizon Europe project that ended on 30 September 2026; its last call round closed in 2024. Kept for reference.
