Job summary

C12 Quantum Electronics is building a hybrid quantum architecture based on spin qubits in carbon nanotubes and high‑impedance cQED. The Qubit Control team designs and optimizes experiments, develops scalable workflows, and collaborates across theory, engineering, and software to scale toward a full QPU.

We value rigorous scientists who can also pragmatically build and automate systems, with a strong emphasis on reproducibility and innovation in a Paris lab setting.

Qualifications

• PhD in quantum physics or related discipline.
• Masters with substantial research experience considered.
• Post-doctoral or industry experience is a plus.
• Hands-on experience with quantum experiments (qubits, DC transport, microwave spectroscopy).

Responsibilities

• Design, calibrate, and optimize DC and microwave experiments in dilution cryostats with state-of-the-art high-frequency control electronics.
• Develop scalable measurement and analysis workflows with increasing autonomy.
• Sustain a close feedback loop with engineering teams to improve device performance.
• Work closely with the theory team to connect experimental observations with physical models.
• Collaborate with the software team to execute our automation roadmap toward a full QPU.
• Deepen understanding of spin qubits in carbon nanotubes integrated within high-impedance cQED architectures.
