Resumo da oferta

Aubervilliers-based internship in experimental physics within the Alice & Bob team. You will contribute to extending broadband flux noise sensing by setting up and operating a cryogenic experiment and collaborating with quantum engineers.

The role emphasizes hands-on laboratory work, design of cryogenic RF measurement chains, and development of Python-based control and analysis software. This is a full-time six-month internship in a dynamic quantum computing startup.

Qualificações

• Proficiency in English is required.
• Prior lab or project experience in RF/microwave measurements or low-temperature physics preferred.
• Solid understanding of magnetic fields, flux and electromagnetic coupling required.
• Familiarity with noise characterization and spectral analysis is a plus.

Responsabilidades

• Develop and set up the flux noise measurement experiment.
• Design and assemble the cryogenic and RF measurement chain (wiring, filtering, amplification, instrumentation).
• Implement and document the measurement and control software in Python.
• Characterise flux noise measurement chips.
• Calibrate the flux-tunable resonators (frequency vs. flux, operating point, PDH lock parameters).
• Measure the flux noise power spectral density and extract the relevant metrics.
• Analyse the limitations to broadband operation.
• Model and measure the feedback loop bandwidth, latencies and noise contributions of the readout chain.
• Identify the dominant physical and instrumental limits across the frequency band.
• Propose and test solutions to extend the measurement bandwidth.
• Evaluate alternative locking, readout or analysis schemes.
• Implement and validate the most promising approaches experimentally.
• Report and share results.
• Document experiments, analyses and conclusions in the team's internal tools.
• Present progress and findings to the HERMES team
