Superconducting Platform Technologies

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 o
