Job summary

Quandela in Paris is seeking a Quantum Information Scientist to join the Device Physics team, modelling quantum dot-phonon interactions and phonon-induced noise in semiconductor photon sources.

You will develop numerical models, run simulations with COMSOL or equivalent tools, and validate results against theory and experiments, with opportunities to advance toward C++ for demanding tasks.

Qualifications

• Master’s or PhD in Physics or closely related field.
• Strong foundations in semiconductor, condensed-matter or related quantum physics.
• Hands-on experience modelling physical systems numerically.
• Experience with FEM, finite-difference or related numerical methods, ideally using COMSOL Multiphysics.
• Python for scientific modelling and data analysis.
• Ability to understand the physics behind a simulation, challenge its assumptions and validate its results.
• Ability to collaborate with both theoretical and experimental researchers.

Responsibilities

• Develop numerical models of quantum dot-phonon interactions and phonon-induced noise.
• Calculate relevant physical quantities, including phonon spectral densities, and integrate them into existing source models.
• Apply finite-element, finite-difference and related numerical methods to semiconductor nanostructures.
• Build and run simulations using COMSOL Multiphysics or comparable platforms.
• Validate your models against physical expectations, existing models and experimental results.
• Develop scientific code primarily in Python, with opportunities to move toward C++ for demanding simulations.
• Use validated models to explore improvements in photon-source design and operation.
