Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
PURPOSE OF THE ROLE
In a context of developing new hardware to host larger chips in line with the company roadmap, the Experimental Quantum Physics Intern develops the sensors and test structures that validate this hardware at cryogenic temperatures.
Reporting to the Team Lead, Cryohardware development, you will work closely with the Cryohardware development team and the Quantum Hardware lead expert to qualify the hardware.
Responsibilities:
- Translate a hardware requirement into what to measure
- Design test structures (e.g. resonators, daisy chains on printed circuit boards (PCB)) and the fixtures that mount them in a dilution refrigerator, up to fabrication files
- Define sample size and statistics, repeatability across cooldowns, and pass/fail criteria
- Estimate test time per unit
- Measure superconducting film properties (critical temperature (Tc), residual resistance ratio (RRR)), microwave losses of resonators and interconnect continuity
- Compare the results with simulations
- Run the same procedure on many samples with traceable data
1. Design test structures and setups
2. Design the test methodology for scale
3. Run the measurement
4. Automate the benches and the analysis in Pytho
Requirements:
- LANGUAGES: Proficient in English
- Proficiency in Python for instrument control and data analysis
A second-year Master’s or final-year engineering student in physics (quantum physics, condensed matter, low-temperature or applied physics), with an interest in experimental design and instrumentation. You are comfortable writing Python to control instruments and analyse data.
Nice to have:
- Experience in cryogenic, electrical or microwave measurements
- Experience with a design tool (e.g. KiCad, mechanical computer-aided design (CAD), microwave simulation)
- EXPERIENCE: No prior professional experience required
Benefits:
- 1 day off per month
- Half of transportation cost coverage (as per French law)
- Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.
You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!
We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
