About Quandela

Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.

Our core product consists of ultra-bright sources of single-photons based on a disruptive technology developed for the past 15 years at the C2N-CNRS laboratory. These unique quantum light sources serve as building blocks for the development of optical quantum computers and the deployment of quantum networks.

During this internship you will be part of the team in charge of the optical characterization of these ultra-bright single-photon sources. In particular, you will be working on:

• Optical spectroscopy of quantum dots
• Characterization of sources using customized optical tools
• Quantitative analysis of key metrics and their optimization
• Design and assembly of advanced optical systems
• Test and characterization of innovative solutions

This internship will allow you to get unique hands-on experience at the intersection of quantum optics (cavity QED), semiconductor physics, and optical engineering, providing a strong foundation for a future career in academic research or cutting-edge photonics and quantum technology engineering.

Requirements

• You are enrolled in a university program that includes an internship period. This should be a Master's Degree (first or second year) or equivalent (not a PhD) program in Physics, Engineering, or related fields
• You are available full-time for 5 to 6 months
• You have background in optics, photonics, or a related discipline
• Experience with Python is a plus
• You want to work in an international team and have good English communication skills
• You are curious, energetic, and love solving problems

Benefits

• Swile Card (meal vouchers)
• 50% participation in transportation cost
• Possibility of remote work
• Internship Allowance between €1,200 and €1,400 per month
• 1,5 days off per month, cumulative
