C12 Quantum Electronics 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 Quantum Electronics 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 Quantum Electronics is a fast-growing start-up that recently raised EUR 18 million in 2024 to further its research in its own lab in the heart of Paris (Panthéon).

You should join us if...
You want to contribute to achieve landmark results in quantum computing, making a difference in the emerging quantum technologies.
You want to work within a 40-people team with various backgrounds in nanofabrication, quantum electronics and carbon nanotube science to materialize our vision of a revolutionary quantum computing processor.
You want to thrive in an exceptional scientific environment with several industrial and academic partners.
You relate to our values (excellence, scientific integrity, diversity, curiosity and care) and want to help us define our product-focus culture and ambition to accelerate.
C12 Quantum Electronics’ unique technology
At C12 Quantum Electronics, 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 Quantum Electronics encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience. Applications from women are particularly welcomed.
