QUANTUM COMPUTING

Led by CSC – IT Center for Science, the deployment will support R and D into faulttolerant quantum and hybrid computing.

The system, named LUMI-IQ, is part of the LUMI AI Factory initiative and is jointly funded by the EuroHPC Joint Undertaking and participating countries Finland, Czechia, Norway and Poland. LUMI-IQ will be hosted in CSC’ s data centre in Kajaani, Finland.

LUMI-IQ will be delivered in three steps: the first installation of an IQM Halocene H4 system in 2027 with 150 physical qubits and early quantum error correction capabilities. The system will be upgraded in 2028 to lower logical error rates and enable real-time error correction. The final upgrade is installation of an IQM Halocene H5 system in 2029. These upgrades equip the system towards early fault-tolerant quantum computing. giving customers a capital-efficient route to benefit from its error correction roadmap.

Logical qubits created by combining multiple physical qubits through quantum error correction are significantly more stable and reliable than physical qubits alone, making them essential to running the longer, more complex calculations required for realworld quantum applications.

“ Owning an upgradeable quantum computer let ´ s CSC and the LUMI AI Factory integrate the system into their own AI and HPC infrastructure. That ' s what lets a real ecosystem grow: researchers building on infrastructure they control, inside one of the most capable computing environments anywhere,” said Jan Goetz, CEO and Co-founder, IQM Quantum Computers.“ That kind of ownership is exactly what Europe needs right now – not just access to quantum computing, but the ability to shape its direction, build local expertise, and push the frontiers of advanced computing.”

The system will be integrated into the LUMI-AI computing environment. Together, LUMI-IQ and LUMI-AI will form a leading hybrid computing platform, enabling workloads that combine HPC, AI and quantum computing.

This integrated approach is expected to enable new forms of scientific workloads that combine traditional simulation, machine learning and quantum algorithms, opening new research avenues for European end-users.

“ The greatest potential lies in combining the complementary strengths of AI, high-performance computing, and quantum computing. Logical qubits make quantum calculations more reliable, while AI and HPC provide the scale, data processing and orchestration needed around them. The LUMI AI Factory allows European researchers to develop innovative hybrid approaches in a world-class computing environment,” said Kimmo Koski, CEO, CSC – IT Center for Science. •

After the final upgrade, LUMI-IQ will be capable of fast real-time feedback sustaining logical qubits and enabling full logical operations between the qubits, including lattice surgery and T-gate teleportation. With distance 3 surface code and colour code, the system will enable computations with up to nine logical qubits.

Additionally, the system is capable of encoding logical qubits up to distance 11 with surface code and distance 9 with colour code.

This phased delivery reflects IQM ' s roadmap towards fault-tolerant quantum computing,
