EuroHPC JU launches procurement for a new quantum computer in Germany

The European High Performance Computing Joint Undertaking (EuroHPC JU) has launched a call for tender for the installation of Euro-Q-Exa, a new EuroHPC quantum computer to be located in Germany.


The Euro-Q-Exa system will be a digital quantum computer based on superconducting qubits and state-of-the-art entangling capabilities that will offer 50 physical qubits in a first stage and at least 100 qubits in a second stage.

The system will be hosted and operated by the Leibniz Supercomputing Centre (LRZ) in Germany and integrated into the LRZ supercomputer SuperMUC-NG.  

The LRZ plans to tightly integrate Euro-Q-Exa quantum computer into its infrastructure. The quantum system will not merely be connected to the HPC network, but integrated into the supercomputer architecture with a unified software environment and user experience.

The Euro-Q-Exa quantum computer will be available to a wide range of European users, from the scientific community to industry and the public sector. The upcoming quantum computing infrastructure will support the development of a wide range of applications with industrial, scientific and societal relevance for Europe, adding new capabilities to the European supercomputing infrastructure.

The acquisition and integration of quantum computers into existing HPC data centres is EuroHPC’s first initiative in directly procuring quantum computing hardware which will be owned by the EuroHPC JU.

In November 2023, the EuroHPC JU also launched a call for proposals on European Quantum Excellence Centres (QECs) to establish knowledge hubs for quantum computing and thus fostering the development of a quantum computing ecosystem. The call is open until 14 May 2024. To complement the upcoming quantum infrastructure, additional calls targeting the development of hybrid HPC-Quantum Computing middleware technologies, as well as hybrid algorithms and applications are planned for the near future, ensuring a holistic approach for the development of a European quantum computing ecosystem.

More details 

The total cost of the system is EUR 42,71 million and will be co-funded by the EuroHPC JU, the Federal Ministry of Education and Research (BMBF) and the Bavarian State Ministry of Science and the Arts. The closing date for submission of an application to tender is the 22nd January 2024 at 16:00 [CET].

On 27 June 2023, the EuroHPC JU signed hosting agreements with six sites across Europe to host & operate EuroHPC quantum computers.

The selection of six hosting entities followed the view of offering the widest possible variety of different European quantum computing platforms and hybrid classical-quantum architectures, giving Europe the opportunity to be at the forefront of this emerging field, and to provide European users with access to diverse and complementary quantum technologies.

This initiative offers a novel interpretation of quantum computers as accelerator platforms in genuine HPC environments. The foreseen integration will require essential R&D developments towards a hybrid software stack managing both HPC and quantum computing workloads.  During the integration work, all Hosting Entities will collaborate closely with European Standardisation bodies.

These six quantum computers will come on top of two analogue quantum simulators currently being deployed within  the EuroHPC JU project HPCQS which are based on neutral atoms, supplied by the French company PASQAL. HPCQS is the first initiative towards a federated European quantum computing infrastructure, tightly integrating two quantum computers, each controlling 100-plus qubits in the Tier-0 HPC systems Joliot-Curie of GENCI and the JUWELS modular supercomputer at the Julich Supercomputing Centre (JSC). 

The EuroHPC JU is a legal and funding entity, created in 2018 and reviewed in 2021 by means of Council Regulation (EU) 2021/1173, with the mission to:

  • develop, deploy, extend and maintain in the EU a world-leading federated, secure and hyper-connected supercomputing, quantum computing, service and data infrastructure ecosystem;
  • support the development and uptake of demand-oriented and user-driven innovative and competitive supercomputing system based on a supply chain that will ensure components, technologies and knowledge limiting the risk of disruptions and the development of a wide range of applications optimised for these systems;
  • widen the use of that supercomputing infrastructure to a large number of public and private users and support the development of key HPC skills for European science and industry.

In order to equip Europe with a world-leading supercomputing infrastructure, the EuroHPC JU has already procured nine supercomputers, located across Europe. Three of these EuroHPC supercomputers are now ranked among the world’s top 10 most powerful supercomputers: LUMI in Finland, Leonardo in Italy and MareNostrum 5 in Spain.
