Paris, France C12 Quantum Electronics Temps plein

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

**Your role in C12 Quantum Electronics**:

- We are seeking a skilled Nanofabrication Engineer to contribute to the fabrication of spin qubit devices. These devices integrate superconducting resonators as well as normal and magnetic electrodes, serving as the foundation for the spin qubits based on carbon nanotubes.
- You will work closely with a multidisciplinary team of researchers and engineers in quantum physics, nanotechnology, and quantum information to develop C12’s hardware platform. This role involves tackling complex, long-term challenges in quantum engineering.
- Key Responsibilities:

- Fabricate spin-qubit devices through standard nanofabrication techniques
- Develop and refine nanofabrication processes to achieve optimal performance
- Establish and maintain precise control over fabrication parameters
- Ensure high throughput and yield of devices on a wafer scale
- Create, update, and maintain comprehensive documentation of fabrication processes
- Analyze and interpret data to drive continuous improvements in fabrication
- Calibrate and maintain equipment, taking full ownership of assigned tools

**About you**:

- Master’s degree in Nanotechnology or Nanoscience, Physics, Engineering, or a related field
- Previous experience in nanofabrication in a cleanroom with a focus on: electron-beam lithography, plasma dry etching (ICP-RIE) and thin film deposition.
- Attention to detail and ability to execute a standard recipe accurately
- Fluency in English is mandatory
