The company

C12 develops a reliable & application-specific quantum computer, to solve highly complex computing tasks, currently out of reach of the 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 (CNT) 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 in the heart of Paris (Panthéon).

Your role

As part of the nanoassembly team at C12, you will be the main operator of the custom nanoassembly apparatus to integrate ultra-pure carbon nanotubes with microchips to create qubits.

• Probe and optically inspect microchips (probe station, SEM)
• Electrically characterise quantum devices
• Analyse, summarise and present data

Requirements

• Master in Electrical Engineering, Physics, Applied Physics, Materials Science or other related field
• Good knowledge of micro electronics and low current measurements
• Basic understanding of good software development practices, Python language, and version control systems
• Hands-on approach ; designing, building and maintaining hardware
• Problem solving and creativity
• Ability to distil and communicate scientific information effectively with the wider team
• Good communication in English (verbal and written)

Preferred traits

• Experience in semiconductors
• Experience with high vacuum systems
• Experience in carbon nanotubes
• Experience with scanning probes
