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.
As part of the quantum measurement team at C12, you will measure and characterize spin qubit devices to achieve quantum operations. In collaboration with other scientists you will:
Work on optimising and automatizing the formation of double quantum dots coupled to microwave resonators
Develop coherent control of spin qubits hosted in carbon nanotubes
Along with our theory team, collaborate in the design and the implementation of optimised readout schemes as long as 1-qubit and 2-qubit gates
Along with our nanofabrication team and RF engineers, participate in the design of the on-chip microwave architecture in order to maximise readout fidelity and qubit coupling
Maintain, specify and build room-temperature DC and high frequency measurement setup (hardware and software)
