Qilimanjaro Launches Europe’s First Multimodal Quantum Data Center in Barcelona

Qilimanjaro Quantum Tech has announced a major new development in the European quantum landscape with the launch of its Quantum Data Center in Barcelona’s innovation district. This new facility is being touted as Europe’s first multimodal quantum infrastructure, establishing Catalonia as a key global hub for quantum computing. The center is designed to host up to 10 quantum computers and is capable of serving thousands of users via Qilimanjaro’s Quantum-as-a-Service (QaaS) platform, SpeQtrum. The Advantage of Multimodality What sets this data center apart is its multimodal approach, offering users access to both digital and analog quantum computers, combined with classical high-performance compute (HPC). This setup allows users to strategically match specific use cases—from simulating new materials to complex optimization—with the most appropriate hardware. Analog quantum computing, which Qilimanjaro specializes in using fluxonium chips, is inherently suited for continuous, complex problems like molecular simulation and physical systems. It also promises powerful new ways to train AI models and tackle large-scale optimization challenges, potentially leading to faster and more energy-efficient computation. Dr. Marta Estarellas, CEO of Qilimanjaro Quantum Tech, emphasized the collaborative vision of the new center: “This center is much more than a technological facility; it is an open ecosystem where industry, research, and public institutions can prepare for the future. Quantum computing is not a distant promise; it is already transforming the way we understand innovation.” Driving European Sovereignty and Growth The initiative is seen as a major step in reinforcing European technological sovereignty and sustainability. By providing organizations across the continent with firsthand, cloud-based access to this unique combination of quantum and classical compute, the center aims to accelerate the exploration of real-world quantum applications. SETT (Spanish Society for Technological Transformation), an early investor, reaffirmed its support, with José María García Orois stating their firm commitment to supporting the company’s growth as it solidifies its position as a leading European reference in quantum technologies. Qilimanjaro, founded in 2019, aims to accelerate the arrival of useful quantum computers by focusing on the development of integrated, error-resilient analog chips based on fluxoniums. The company argues that its analog systems offer immediate advantages in simulation, optimization, and AI—areas where purely digital quantum processors still face significant limitations in scalability and error tolerance. The new Quantum Data Center, alongside Qilimanjaro’s dual strategy of offering both remote QaaS access and on-premise systems, symbolizes a new era for European technology, promoting collaboration to build a sustainable, responsible future driven by advanced computational resources.
