We are always looking for new talent to join our team!

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 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 minimizes 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 revolutionized classical computing.

Founded in 2020, C12 is a fast-growing start-up, having raised a seed round of USD 10 million in June 2021 and building its own lab space in the center of Paris.

C12’s unique technology

At C12, a qubit, the fundamental functional unit of a quantum computer, is built from an ultra-pure carbon nanotube suspended above a silicon chip containing control electrodes and a quantum communication bus. Spin qubits coupled to a microwave cavity brings interesting perspectives for their 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).
