Description of the Team

The internship will be conducted in the Photonic Integrated Circuits (PICs) department ofQuandela. The PICs team works on the production and development of the optical processors of Quandela quantum computers, having in mind performance and scalability.

In detail, the team members carry out electromagnetic and thermal simulations to estimate the performance of the integrated components, prepare PICs layouts to be fabricated in collaboration with external foundries, and take care of both the characterization and the packaging of the fabricated devices.

Your Key Responsibilities

Depending on your experience and the duration of the internship, your work may involve deepening the understanding of existing building blocks, exploring new functionalities or tools, or developing advanced modeling approaches for testing. In particular, the goal of this internship will be to either bridge the gap between fabrication and design, or to evaluate new architecture for quantum processing unit (QPU).

In this role you will be using standard electromagnetic simulations and/or circuit modelling by means of commercial software like Lumerical FDTD, FDE, EME or free-tools (gdsfactory, tidy3d, meow, sax..).

Requirements

• Enrollment for the whole duration of the internship in a MSc in Physics, Telecom/Electronics Engineering, Photonics, Quantum Technologies or related fields. This position is only valid with an Internship Agreement.
• Minimal duration is 5 months. Shorter internship will not be accepted.
• Ideal starting date late Summer 2026.
• General knowledge of integrated photonics modelling and layout
• Python, Git, Lumerical, simulation tools (FDTD, mode solver, EME..)
• Great skills in data analysis
• Capability of working in a team
• Strong communication skills in English and French
