Luxembourg quantum funding: €79 million EuroHPC calls open

Europe is actively pushing to secure its digital sovereignty and transition scientific breakthroughs into real market opportunities. Under the Quantum Europe Strategy, adopted by the European Commission in July 2025, the EU aims to position itself as a global leader in quantum technologies by 2030. The strategy addresses the historical fragmentation across Member States by focusing on five key areas: research and innovation, quantum infrastructures, ecosystem strengthening, space and dual-use capabilities, and quantum skills.

To execute this vision, the European High-Performance Computing Joint Undertaking (EuroHPC JU) has allocated substantial funding to bridge the gap between academic research and industrial deployment. Six strategic calls are currently open, representing a combined budget of €119 million. These calls target critical technical roadblocks, from scaling physical qubits to establishing robust testing and pilot production lines.

These funding opportunities will be funded under Horizon Europe as Research and Innovation Actions, which means a 100% funding rate grant for activities starting in industrial research and ending in experimental development. They opened for submission on 13 August 2026, and the strict deadline for submitting proposals is 17 November 2026. Discover four of these calls and how we can help you apply for them.

Four open EuroHPC quantum calls

Superconducting Platform Technologies

HORIZON-JU-EUROHPC-2026-SPT-10-01 - With a budget of €20 million, this call aims to develop a cloud-accessible, full-stack superconducting quantum computer targeting 1,000 physical qubits and quantum processing unit architecture based on chiplet technology, advancing systems from Technology Readiness Level (TRL) 4 to TRL 7.

Next-Generation QKD Systems

HORIZON-JU-EUROHPC-2026-NQKD-12-01 - This €24 million call focuses on quantum-secure communications by developing next-generation Quantum Key Distribution (QKD) systems with key rates exceeding 1 Mbps over metropolitan distances and regional network coverage of more than 300 km, while implementing advanced cryptographic protocols beyond QKD, including by combining QKD and post-quantum cryptography. The systems should advance from TRL 4 to 7.

Quantum-Testing Infrastructure for Quantum Technologies

HORIZON-JU-EUROHPC-2026-QTI-13-01 - Backed by a €20 million budget, this action will establish a pan-European, open-access testing and experimentation infrastructure for quantum technologies to validate and certify quantum components and systems. The systems should advance from TRL 3/4 to 5/7.

Quantum Experimental Pilot Lines for Quantum Technologies

HORIZON-JU-EUROHPC-2026-QEXP-14-01 - This €15 million call (Qu-Pilot) aims to establish experimental production infrastructure to advance quantum hardware technologies, focusing on quantum processors, sensors, and cryo-compatible packaging. The system should advance from TRL 3/4 to TRL 5/7.
