Barcelona goes Quantum with 100% European Technologies

The new system will be available to the research community, companies and public organisations in Spain

The construction and implementation of this infrastructure is part of the Quantum Spain initiative, promoted by the Ministry for Digital Transformation and Civil Service through SEDIA.

The Barcelona Supercomputing Center – Centro Nacional de Supercomputación (BSC-CNS) has presented the first quantum computer developed with 100% European technology. This milestone consolidates BSC at the forefront of supercomputing in Europe and lays the foundations for a new era of hybrid computing, combining traditional and quantum computing.

The new system is part of Quantum Spain, an initiative coordinated by BSC and promoted by the Ministry for Digital Transformation and Public Administration, through the State Secretariat for Digitalisation and Artificial Intelligence (SEDIA). Funded by the Recovery, Transformation and Resilience Plan, the initiative is part of the Digital Spain 2026 programme and the National Artificial Intelligence Strategy (ENIA).

Quantum Spain is a collaborative effort involving 27 leading research and supercomputing institutions in Spain, including the 14 nodes of the Spanish Supercomputing Network (RES) and other institutions such as CSIC, ICFO and universities such as the University of Barcelona, the Autonomous University of Madrid and the Polytechnic University of Valencia, among many others.

The new quantum infrastructure will be integrated into MareNostrum 5

The new quantum computer was presented today, at an event held in the Torre Girona chapel, where the BSC installed the first four versions of the MareNostrum and now houses the new quantum infrastructure that will be integrated into MareNostrum 5, the most powerful supercomputer in Spain and one of the most advanced in the world.
