Open EU call topic HORIZON-JU-EUROHPC-2026-SPT-10-01 · HORIZON JU Research and Innovation Actions. Part of call HORIZON-JU-EUROHPC-2026-SPT-10: Superconducting Platform Technologies. Next deadline 2026-11-17. Topic page: https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-details/HORIZON-JU-EUROHPC-2026-SPT-10-01

Expected Outcome: This action will consolidate Europe’s position in superconducting quantum computing through: - Establishment of a full-stack superconducting quantum computer aiming at 1.000 physical qubits and QPU architecture based on chiplet technology. The system should feature a scalable and user-adjustable architecture, T1 coherence time above 100 us, gate fidelities (both one- and two-qubit gates, and read-out) of at least 99.9%, read-out speed below 300 ns, two-qubit gate speed below 20 ns. - Demonstration of quantum advantage on selected industrial use cases, validated through benchmarking with best-in-class classical methods. - Deployment of a cloud-accessible quantum system integrated with high-performance computing environments. - Maturation of fault-tolerant quantum computing protocols, including effective quantum error correction and noise mitigation schemes. - Delivery of a comprehensive, standardised software stack supporting system bring-up, calibration, control, benchmarking, and user access.

Strengthened supply chains and industrial capacity in Europe for superconducting quantum technologies. Scope: The proposal should contribute to the scale-up and practical deployment of superconducting quantum computing platforms and must address at least two of the critical technical roadblocks identified in the SRIA 2030, among which necessarily: - Error Correction and Fault Tolerance: the implementation of error correction and fault-tolerant quantum computing via significant improvements in gate fidelity, coherence times, and noise mitigation strategies. - Cryogenic and Interconnect Engineering: integration…
