C12 develops reliable & application-specific quantum computers, to solve highly complex computing tasks, currently out of reach of even most powerful supercomputers. Building a quantum computer still needs innovators ready to tackle exciting challenges. C12’s founders are convinced that only a new material for the qubit will bring a technological breakthrough. C12 uniquely uses carbon nanotubes as the fundamental building blocks of its quantum processor. This high-purity material minimises errors, radically improves performance and reduces hardware overhead for fault-tolerant computing. Combined with well-established semiconductor techniques, carbon nanotubes will help scale quantum computing, just as silicon revolutionised classical computing. Founded in 2020, C12 is a fast-growing start-up, who recently raised EUR 18 million in 2024 to further its research in its own lab in the heart of Paris (Panthéon).

C12’s Quantum Electronics' unique technology
At C12, a qubit, the fundamental functional unit of a quantum computer, is built from an isotopically ultra-pure 12C nanotube suspended above a silicon chip containing control electrodes and a quantum communication bus. Our spin qubits hold great promises in terms of individual control and manipulation as well as for the circuit architecture. A suspended isotopically pure 12C nanotube holds great promises in terms of stability, as it reduces all sources of decoherence (charge noise, nuclear spin noise, phonon relaxation).
C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience. Applications from women are particularly welcomed.
