Marketing & Communications Intern / Apprentice

C12 develops reliable & application-specific quantum computers to solve complex computing tasks currently out of reach of even the most powerful supercomputers. Building a quantum computer still needs innovators who are ready to tackle exciting challenges. At C12 we are convinced that a new material for the qubit will bring a technological breakthrough. At C12 the fundamental building block of the quantum processora qubitis constructed using ultra-pure carbon nanotubes suspended above a silicon chip with control electrodes and superconducting resonators . This high-purity material minimises errors enhances performance and reduces hardware overhead for fault-tolerant computing. Spin qubits coupled to a microwave resonator offer exciting possibilities for control manipulation and circuit architecture. The suspended isotopically pure 12C nanotube significantly improves stability by reducing sources of decoherence such as charge noise nuclear spin noise and phonon relaxation. Leveraging well-established semiconductor techniques carbon nanotubes hold great promise for scaling quantum computing much like silicon in 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 (Panthon).

C12 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 promise in terms of individual control and manipulation as well as for the circuit architecture. A suspended isotopically-pure 12C nanotube holds great promise in terms of stability as it reduces all sources of decoherence (charge noise nuclear spin noise and phonon relaxation).

C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications skills knowledge and from women are particularly welcomed.
