The EuroHPC Joint Undertaking has inaugurated EuroQCS-Spain, a new EuroHPC quantum computer located at Barcelona Supercomputing Center in Spain. Hosted and operated by Barcelona Supercomputing Center-Centro Nacional de Supercomputación, EuroQCS-Spain is supplied by Qilimanjaro Quantum Tech and Do IT Now. The system is an analogue quantum computer designed to implement quantum annealing routines, a computational approach used for certain optimization problems involving complex solution spaces.
The first-generation EuroQCS-Spain system will offer 10 physical qubits, with planned upgrades expected to improve coherence times and increase the number of data qubits. The system is undergoing final calibration at Barcelona Supercomputing Center, with end-user onboarding expected shortly.
EuroQCS-Spain will be integrated into MareNostrum 5, one of Europe’s EuroHPC pre-exascale supercomputers. This integration is intended to support a hybrid classical-quantum architecture accessible to European researchers, industry users, and public-sector organizations.
EuroQCS-Spain, located inside the Torre Girona chapel at Barcelona Supercomputing Center, strengthens Europe’s hybrid classical-quantum computing infrastructure through integration with MareNostrum 5.
The system is located in the Torre Girona chapel, the distinctive facility that houses Barcelona Supercomputing Center’s MareNostrum infrastructure. The setting reflects the broader role of BSC as a European high-performance computing hub and as one of the hosting entities supporting EuroHPC JU’s large-scale investment in advanced computing infrastructure.
Quantum annealing is designed for optimization problems in which a system evolves from an initial state toward a final state representing an optimal solution. This approach may be useful for applications involving logistics optimization, finance, molecular modeling, physical phenomena, quantum machine learning, and AI model training.
EuroQCS-Spain is owned by EuroHPC JU and co-funded with a total acquisition cost of 8.5 million euros. EuroHPC JU will fund 50% of the cost, with the remaining 50% funded by Spain’s Ministry for Digital Transformation and the Civil Service, complemented by a contribution from Portugal. The system is expected to operate for three years.
The inauguration also reflects EuroHPC JU’s broader effort to deploy a sovereign and state-of-the-art quantum computing infrastructure across Europe. To date, EuroHPC JU has procured six quantum computers located across Europe. Four systems have already been inaugurated since last year: PIAST-Q in Poznań, Poland; VLQ in Ostrava, Czechia; Euro-Q-Exa in Munich, Germany; and Lucy near Paris, France.
Together, these systems are intended to provide European users with access to a wide variety of quantum computing platforms and hybrid classical-quantum architectures. The EuroHPC JU deployment strategy includes technologies such as analogue quantum simulators based on neutral atoms, trapped ions, superconducting circuits, photonics, and adiabatic systems capable of executing annealing routines.
In addition to the six EuroHPC quantum computers, two analogue quantum simulators, Jade and Ruby, have been procured under the EuroHPC JU HPCQS project and inaugurated in Germany and France. Additional procurement processes are also underway for EuroHPC quantum computers to be hosted and operated by SURF in the Netherlands and LuxProvide in Luxembourg.
The EuroQCS-Spain deployment supports Europe’s objective of expanding access to advanced computing infrastructure for science, industry, and public-sector applications. By integrating quantum annealing capabilities with MareNostrum 5, the project creates a pathway for researchers and commercial users to explore hybrid workflows that combine classical high-performance computing with emerging quantum technologies.
About EuroHPC JU
The EuroHPC Joint Undertaking is a legal and funding entity that brings together the European Union and participating countries to coordinate investment and pool resources in high-performance computing, quantum computing, and advanced digital infrastructure. EuroHPC JU’s objective is to make Europe a global leader in supercomputing while supporting European scientific, industrial, and public-sector users.
EuroHPC JU has procured supercomputers across Europe and provides access to these systems through EuroHPC Access Calls. Its activities also include support for research and innovation projects across the European supercomputing supply chain, including processors, software, applications, and advanced computing expertise. With the adoption of Council Regulation (EU) 2026/150, EuroHPC JU’s mandate has been expanded to include new action pillars for AI Gigafactories and quantum technologies.
