The European Commission decided to cancel three quantum topics from the Horizon Europe Cluster 4 work programme 2026-2027. The topics in call HORIZON-CL4-2026-04 are currently suspended while an amendment to the work programme is being finalised, which is currently foreseen in the fourth quarter of 2026. The submission platform for these topics is no longer accessible, and participants preparing or submitting proposals have already been informed.
The intention is to relaunch these call topics under the EuroHPC Joint Undertaking, which will be mandated to include, among other things, also quantum technologies.
The suspended topics are
- HORIZON-CL4-2026-04-DIGITAL-EMERGING-11 on quantum sensors for inertial navigation,
- HORIZON-CL4-2026-04-DIGITAL-EMERGING-12 on standards for quantum technologies as a coordination and support action, and
- HORIZON-CL4-2026-04-DIGITAL-EMERGING-18 on large-scale photonic quantum computing platform technologies as a research and innovation action.
Further information is expected from EuroHPC JU, including updates on possible future calls: https://eurohpc-ju.europa.eu and https://eurohpc-ju.europa.eu/about-eurohpc-ju_en.
