Résumé du poste

C12 Quantum Electronics, Paris, is seeking a PhD-qualified experimentalist to advance spin qubit control in carbon nanotube devices. You will design and calibrate DC and microwave experiments, develop reproducible workflows, and collaborate with theory, software, and engineering teams to scale toward a practical quantum processing unit.

You will contribute to automated, high‑quality data analysis and maintain rigorous scientific standards while mentoring junior researchers in a fast‑moving,

Qualifications

• You are driven by the scientific and engineering challenge of building a quantum computer, and you want to contribute to a meaningful milestone in the field.
• You hold a PhD (or Masters with substantial research experience) in quantum physics or a closely related discipline, you have additional experience as post-doctoral researcher or in the industry.
• You have hands‑on experience with quantum experiments — qubits, DC transport, microwave spectroscopy, ...
• You write Python fluently and use it autonomously to control experiments, process data, and build reusable tools.
• You hold yourself to high scientific standards and are equally motivated by results.
• You communicate clearly in English, in writing and in conversation, across technical and non-technical audiences.
• You have experience in mentoring and supervising PhD students or interns.
• You have experience working in a company in a similar domain.

Responsabilités

• Design, calibrate, and optimise DC and microwave experiments in dilution cryostats equipped with state-of-the-art high-frequency control electronics.
• Develop scalable measurement and analysis workflows: well-documented, reproducible, and built to run with increasing autonomy.
• Sustain a close feedback loop with engineering teams to continuously improve device performance.
• Work closely with the theory team to connect experimental observations with physical models.
• Actively collaborate with the software team to execute our automation roadmap — from experiment scheduling to data analysis — as we scale toward a full QPU.
• Deepen our understanding of spin qubits in carbon nanotubes integrated within high-impedance cQED architectures.
