Spain, Unknown – January 25, 2026 — Barcelona, Catalonia – In a landmark advancement for digital security, specialists in Catalonia have established Europe’s inaugural quantum-safe data centers, drawing 500 million euros from European Union funds to fortify infrastructure against emerging computational threats. This initiative, centred in Barcelona’s vibrant Sant Martí technology district, integrates cutting-edge quantum-resistant encryption protocols with hybrid computing systems, ensuring long-term protection for sensitive data across industries.
The project, spearheaded by Qilimanjaro Quantum Tech in partnership with local innovators and Oxigen Data Center, spans a 1,000-square-metre facility designed to accommodate up to 15 quantum processors over the next few years. Initial operations feature four advanced units, blending analogue and digital modalities to deliver resilient computing power. These systems employ specialised algorithms that withstand potential disruptions from future quantum advancements, safeguarding financial transactions, healthcare records, and energy grids. By early 2026, the centres aim to support thousands of users through a dedicated Quantum-as-a-Service platform, fostering widespread access to secure processing.
Dr. Marta Estarellas, chief executive of Qilimanjaro Quantum Tech, highlighted the forward-thinking approach during a recent facility tour. “This infrastructure represents a collaborative triumph, uniting businesses, researchers, and institutions to build a secure digital tomorrow. Quantum-safe measures are now essential, transforming potential vulnerabilities into opportunities for innovation,” she remarked. The centres’ design prioritises energy efficiency, with cooling systems optimised for high-density operations and integration pathways for classical high-performance computing.
Catalonia’s government has played a pivotal role, providing grants through agencies like Avançsa and ACCIÓ to accelerate development. Miquel Sàmper, Minister for Business and Labour, praised the effort at the project’s milestone event on 6 November 2025. “Such endeavours showcase Catalonia’s prowess in nurturing talent and investment, creating a dynamic ecosystem that generates high-quality jobs and drives technological leadership,” he stated. The 500 million euro EU allocation, part of broader resilience programmes, underscores confidence in Barcelona’s capacity to lead continental progress.
Complementing this, the Barcelona Supercomputing Center has advanced hybrid setups by incorporating fully European-developed quantum systems into its MareNostrum 5 supercomputer. Unveiled in February 2025, these additions enhance computational capabilities while embedding quantum-safe features, supported by national initiatives like Quantum Spain. Officials including Catalan President Salvador Illa and Minister of Science Diana Morant attended the presentation, celebrating the alignment with Digital Spain 2026 goals.
Community and industry responses reflect enthusiasm for the positive momentum. Local firms in pharmaceuticals and logistics anticipate faster simulations of complex molecules and optimised supply chains, thanks to the centres’ prowess in handling intricate problems with reduced energy demands. Nine industrial doctorate programmes have already trained specialists, bolstering the workforce with expertise in quantum integration. Repsol and ICO-backed financing of 10 million euros has enabled office expansions and talent recruitment, employing over 70 professionals.
Looking ahead, collaborations like the December 2025 agreement between Qilimanjaro and Oxigen Data Center promise seamless fusion of quantum elements into commercial environments. This partnership explores hybrid architectures, positioning Barcelona as a nexus for quantum cloud services. By mid-2026, expansions could double capacity, inviting more enterprises to leverage secure, scalable resources.
The initiative’s emphasis on sustainability aligns with regional priorities, utilising renewable energy sources and modular designs for adaptability. Experts foresee broader economic benefits, including job creation in advanced engineering and stimulation of startup ecosystems. As Europe advances toward unified digital standards, these quantum-safe data centres exemplify proactive strategies, enhancing trust in data handling and paving the way for innovative applications in climate modelling and personalised medicine.
This development not only elevates Catalonia’s profile but also contributes to continental self-reliance in critical technologies. With rigorous testing phases concluding successfully by January 2026, the centres stand ready to empower businesses and public services, marking a constructive chapter in Europe’s technological evolution. Stakeholders across the region express optimism, viewing the project as a model for sustainable, secure progress.
