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).
C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience.
We are looking for a nanofabrication engineer for the fabrication of printed circuits chips in our cleanroom. These printed circuits enable the control & read-out of our qubits and include superconducting resonators as well as superconducting & magnetic gate electrodes.
Your job will involve:
Nanofabrication of quantum devices
Identification of potential limiting factors to the precise control of nanofabrication
Maintain and ensure the throughput and the yield of the wafer production
Working closely with other teams to improve the overall circuit performance
Creating, developing and maintaining the process documentation
You will collaborate with researchers and engineers (in quantum physics, nanotechnologies and quantum information) to develop the hardware platform of C12. You will be involved in solving complex, long-term quantum engineering challenges.
- Electron-beam lithography of precisely defined sub-micron features (highly-appreciated)
- Wafer-scale photolithography with a micron-resolution
- Experience of developing and improving new nanofabrication recipes
