Barcelona-based Qilimanjaro Quantum Tech is the sole Spanish firm selected for Phase 1 of the EuroHPC Quantum Grand Challenge, chosen from 27 eligible proposals alongside 12 other European quantum companies. The company’s EuroQ-Stack project will map a path for integrating its analog and multimodal quantum computing technology into hyperscale data centers, focusing on the convergence of AI, high-performance computing, and quantum processing.
“The project sets out what industrial-scale quantum computing infrastructure requires,” says Qilimanjaro, with successful completion of Phase 1 potentially unlocking up to 30 million euros in venture debt from the European Investment Bank. This selection also awards Qilimanjaro the STEP Seal, recognizing EuroQ-Stack as a high-quality strategic technology project for Europe.
EuroQ-Stack Roadmap for Hyperscale Data Center Quantum Integration
This distinction acknowledges EuroQ-Stack, Qilimanjaro’s project, as a high-quality strategic technology that will bolster Europe’s technological independence and competitiveness. EuroQ-Stack specifically addresses the integration of Qilimanjaro’s quantum technology into hyperscale data center environments, building upon the company’s existing experience connecting quantum systems to European High Performance Computing infrastructure.
The project will map a detailed technical, commercial, and financial roadmap for this integration, focusing on applications that deliver high value, the specific requirements for hyperscale deployment, and how to ensure a resilient European supply chain. Qilimanjaro’s approach centers on combining analog and multimodal quantum computing, a strategy reflected in its SpeQtrum quantum-as-a-service platform, unveiled in November 2025 and housing fluxonium analog and digital QPUs alongside classical HPC resources.
The company’s technology uses coherent quantum annealing, an alternative to the D-Wave approach, and is supported by a contract signed in early 2025 to supply the MareNostrum-Ona quantum annealer to the Barcelona Supercomputing Center. Qilimanjaro’s partnership with the Open Quantum Institute, a CERN-hosted initiative, further demonstrates its commitment to widening access to quantum computing resources globally, while a parallel research collaboration with VTT through the Qu-Pilot project aims to scale quantum processors, the company says. This strategic alignment positions Qilimanjaro to contribute to establishing a stronger, more sovereign European quantum ecosystem.
QiliSDK Integrates NVIDIA CUDA-Q for Multimodal Quantum Computing
Qilimanjaro’s QiliSDK now supports NVIDIA CUDA-Q, enabling developers to emulate quantum algorithms on graphics processing units and accelerating the path toward hybrid quantum-classical workflows. This integration expands the reach of QiliSDK beyond Qilimanjaro’s own quantum processing units, allowing for broader testing and optimization of algorithms before deployment on actual quantum hardware, according to the company. The move reflects a growing trend toward software tools that bridge the gap between classical and quantum computing environments, essential for scaling quantum applications.
This builds on the company’s November 2025 unveiling of Europe’s first multimodal quantum data center in Barcelona, offering access to fluxonium analog QPUs, digital QPUs, and classical HPC resources through its SpeQtrum quantum-as-a-service platform. Founded in 2019, Qilimanjaro has raised over €24 million in funding and partnered with organizations like CERN’s Open Quantum Institute and VTT Technical Research Centre of Finland, demonstrating a commitment to both fundamental research and industrial applications.
