Barcelona, Spain-based quantum computing startup Qilimanjaro Quantum Tech has secured €19.6 million in the first close of its Series A funding round to expand production of its quantum computing systems.
The financing was led by Indra Group, which invested €10 million through IndraMind, its technology initiative focused on AI and security applications. The Spanish Society for Technological Transformation (SETT), a public entity under Spain’s Ministry for Digital Transformation and Public Administration, contributed an additional €9.6 million.
Qilimanjaro expects to complete the round in the final quarter of 2026, with participation from Avançsa and other existing investors.
Developing Analog and Digital Quantum Computers
Founded in Barcelona in 2019, Qilimanjaro develops quantum computing systems that combine analog and digital processors based on superconducting fluxonium qubits.
The company designs its own quantum chips, software and algorithms while integrating cryogenic systems and control electronics to build complete quantum computers.
Its multimodal approach combines quantum processors with high-performance classical computing infrastructure, allowing different computing architectures to be used for optimisation, simulation and AI applications.
Qilimanjaro has deployed eight quantum systems to date, including three integrated into the Barcelona Supercomputing Center (BSC-CNS). One of these is the first analog quantum computer integrated into a European high-performance computing centre.
The company works with customers in energy, telecommunications, logistics, healthcare and finance, providing on-premise quantum systems, remote access through its SpeQtrum Cloud platform and specialised adoption services.
Scaling Manufacturing and Next-Generation Chips
Qilimanjaro will use the Series A financing to industrialise its quantum computers, develop new generations of chips and increase its manufacturing and deployment capacity.
The investment also supports the company’s efforts to expand quantum computing capabilities developed in Spain and strengthen Europe’s domestic technology infrastructure.
“SETT’s renewed commitment and Indra’s entry bring together sovereign capital and industrial capital to protect, but also accelerate, national technological autonomy. Together, we are joining forces to bring quantum computing closer to strategic industrial sectors and to ensure that the quantum technology built in Spain continues to grow in Spain.”
— Marta P. Estarellas, CEO of Qilimanjaro Quantum Tech
The investment brings Indra Group into Qilimanjaro’s shareholder base alongside SETT, with additional participation expected when the Series A reaches its final close.
