French startup Quandela has launched its Belenos quantum processor in May 2025, featuring 12 qubits. Quandela says the new system delivers 4,000 times more computing power than its 2022 predecessor.
Key Details:
Belenos is accessible via the cloud to over 1,200 users across 30 countries and will be deployed in CEA's Très Grand Centre de Calcul supercomputing center by the end of 2025 as part of the EuroHPC/GENCI initiative. Quandela plans to double qubits again in 2026 with its next system, Canopus, targeting a 16 million-fold power increase relative to its original platform and aiming for a >40-qubit machine within three years.
Quandela plans to launch general-purpose quantum computing libraries for application developers in 2028. In terms of software and algorithms, Quandela aims to boost artificial intelligence applications by developing QPU-GPU hybridization from 2025 and by creating compilers and decoders for error correction by 2027.
The company is also working towards Diadem processors with logical qubits, aiming to reduce error rates by combining multiple physical qubits into one logical qubit.
