The European High Performance Computing Joint Undertaking (EuroHPC JU) has put out six calls across a range of quantum computing technologies.

The projects aim to accelerate the development and deployment of next-generation quantum computers and will have a total funding budget of €119 million ($138m).

The six projects will individually focus on trapped-ion, superconducting, and neutral-atom quantum computing, alongside next-generation Quantum Key Distribution (QKD) technologies, quantum testing infrastructure, and quantum experimental pilot lines.

Dubbed HORIZON-JU-EUROHPC-2026-TIPT-09, the trapped-ion project will target the development of a full-stack, trapped-ion quantum computer with more than 1,000 individually addressable physical qubits. Once complete, the system will be fully integrated with classical high-performance computing systems and accessible via cloud platforms.

Meanwhile, the superconducting HORIZON-JU-EUROHPC-2026-SPT-10 project aims to advance Europe’s superconducting quantum computing capabilities by developing a QPU with at least 1,000 individually addressable physical qubits based on chiplet technology facilitating long coherence times, fast read-outs, and error correction capabilities.

The HORIZON-JU-EUROHPC-2026-NAPT-11 project will focus on advancing neutral-atom quantum technologies by delivering scalable, industry-ready quantum processors for simulation and computing, including the development of fully programmable platforms with 10,000 neutral atoms for simulation and 1,000 physical qubits for computing, with a tangible scaling trajectory up to 10,000 physical qubits.

In an effort to strengthen quantum-secure communications, the HORIZON-JU-EUROHPC-2026-NQKD-12 project will focus on developing next-generation QKD systems with measurable improvements in key rates over metropolitan distances and operational coverage of networks on a regional scale.

The HORIZON-JU-EUROHPC-2026-QTI-13 project will establish a pan-European open-access testing infrastructure for quantum technologies, creating a comprehensive framework for systematic validation and certification of quantum components and systems.

Finally, in order to bridge the gap between academic quantum research and established pilot lines under the European Union’s CHIPS Joint Undertaking, the HORIZON-JU-EUROHPC-2026-QEXP-14 project will establish Qu-Pilot, which will function as a testbed for developing and validating quantum technologies, focusing on technological innovation, manufacturing reproducibility, and scalability.

The trapped-ion, superconducting, neutral-atom, and quantum testing projects all have a budget of €20 million ($23m), while the QKD and experimental pilot line projects will have budgets of €24 million ($28m) and €15 million ($17m), respectively.

The application deadline for the calls is November 17, 2026.
