Job Summary
C12 Quantum Electronics is developing a hybrid quantum architecture based on spin qubits in carbon nanotubes coupled through a circuit quantum electrodynamics (cQED) platform. Our approach combines the exceptional coherence properties of carbon-based qubits with high-connectivity microwave architectures with the goal of building a fault-tolerant quantum processing unit.
The Qubit Control team sits at the heart of this effort. We develop the methods that make qubits work: tuning protocols readout strategies gate implementations. We optimise the control and readout electronics and protocols explore large parameter spaces investigate the physics of the spin qubit and translate physical insight into engineering solutions.
Working at the intersection of quantum physics engineering and software you will collaborate daily with theory and the other engineering teams all co-located in our Paris lab to make those interactions as direct and continuous as possible.
A company at an inflection point:C12 is transitioning from a phase of scientific discovery and proof-of-concept demonstrations to one of systematic scaling. This means our focus is shifting towards automation reproducibility and process maturity without sacrificing the scientific rigor and curiosity that got us here. It is a demanding and exciting moment: we are still making new science while simultaneously building the infrastructure that will carry us to a quantum advantage demonstration. The person joining this team will need to be both a rigorous scientist and a pragmatic builder.
- You will design calibrate and optimize DC and microwave experiments in dilution cryostats equipped with state-of-the-art high-frequency control electronics
- You will develop scalable measurement and analysis workflows: well-documented reproducible and built to run with increasing autonomy
- You will sustain a close feedback loop with engineering teams to continuously improve device performance
- You will work closely with the theory team to connect experimental observations with physical models
- You will actively collaborate with the software team to execute our automation roadmap from experiment scheduling to data analysis as we scale toward a full QPU
- You will deepen our understanding of spin qubits in carbon nanotubes integrated within high-impedance cQED architectures
- 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
- 66000 euros - 78000 euros yearly base salary
- Stock options for every employee (BSPCE/ESOP)
- Sponsored tripto conferences around the world
- A highly dynamicinternational team
- Swile meal vouchers
- Mental health support with
- Training budget/ Annual Learning & Development Allowance
- Sabbatical leave (after 2 years in the company)
- Vibrant office culture (two office spaces in the heart of Paris team lunches offsite events Friday breakfasts..)
- You like hands-on work and technology
- You want to contribute to achieving landmark results in quantum computing making a difference in the emerging quantum technologies
- You want to work within a team of 80 people with various backgrounds in nanofabrication quantum electronics and carbon nanotube science to create a revolutionary quantum computing processor
- You want to thrive in an exceptional scientific environment with several industrial and academic partners
- You share our values (excellence scientific integrity diversity curiosity and care) and want to help us define our product-focused culture and ambition to accelerate
