Digital Twin & Surrogate Modelling Intern M/F (Quantum Computing)

Location: Hybrid, Paris, France

Company

Alice & Bob is developing a universal, fault-tolerant quantum computer based on superconducting Schrödinger cat qubits with autonomous quantum error correction.

What you will do

• Develop fast surrogate models and assess their accuracy, uncertainty, and domain of validity for high-fidelity simulations.
• Implement data assimilation methods that connect experimental measurements with simulations and quantify model and measurement uncertainties.
• Run the team's high-fidelity simulation tools, interpret results, and compare simulation outputs with experimental data.
• Write clean, tested, and documented Python/JAX software and contribute reusable components to a future digital-twin framework.
• Present results and methodological choices while collaborating with simulation, experimental, and design teams.

Requirements

• Final year of a Master's degree (M2) or engineering school in physics, applied mathematics, or scientific computing.
• Proficient English.
• Interest in scientific software, the ability to structure an open-ended problem, work autonomously, and keep the team informed.
• Background in engineering and solid foundations in numerical analysis and numerical methods.
• Knowledge of data assimilation methods, including uncertainty quantification, and reduced-order modelling.
• Experience with open-source scientific simulation software.
• Proficiency in Python with strong experience in JAX.
• Good software engineering practices, including Git, testing, documentation, CI/CD, and verification and validation (V&V).
• Rigour, autonomy, curiosity, and the ability to explain technical choices clearly. No professional experience is required; coursework and research projects can provide relevant skills.

Nice to have

• A previous internship or research project in scientific computing or numerical simulation.
• Statistics or Bayesian inference.
• Experience with PyTorch or TensorFlow.
• Deep learning, quantum physics, or circuit engineering.
• Rigorous use of agentic workflows for scientific research and implementation.

Culture & Benefits

• One day off per month.
• Half of transportation costs covered according to French law.
• Meal vouchers through Swile.
• Fully equipped and regularly stocked kitchen.
• International team of more than 250 people from over 35 countries, with opportunities to share knowledge, innovate, and develop new ideas.
