AMO Physicist, Neutral-Atom Systems and Optical Tweezers for Quantum Networking at Welinq, Paris
Job Description
Welinq is hiring an AMO physicist for its Next-Generation Technology Team in Paris to develop optical-tweezer platforms for quantum networking. You will design, build, optimise and integrate neutral-atom hardware (trapping, transporting and manipulating atoms) and its use inside neutral-atom quantum processors, and help optimise Welinq’s qubit–photon interface, the component that lets quantum processors exchange quantum information over light. The devices you develop form the core of Welinq’s quantum networking products.

How to prepare for this application
- Read Welinq's 2026 announcements on networked quantum computing with Pasqal and OVHcloud to understand the product direction.
- Prepare a clear account of an optical-tweezer or atom-array experiment you ran, including what limited its performance.
- Think about how a qubit–photon interface is characterised (efficiency, fidelity, rate) and be ready to discuss it.
- Bring analysis or control code you wrote for your experiments.
