Quantum Optics Scientist, Spin-Based Quantum Systems, Quandela (Palaiseau, France)
Job Description
This quantum optics scientist job is in Quandela’s Semiconductor Optics Team near Paris. You will run experiments on spin-photon sources and build photon-mediated entanglement between spins. It suits an experimental physicist with a PhD and solid postdoc or R&D experience.
At a glance
- Role: Quantum Optics Scientist – Spin-Based Quantum Systems
- Team: Research, Semiconductor Optics Team
- Where: IPVF campus, Palaiseau (Paris-Saclay), France; on site, full time
- Pay: Not stated; benefits include profit-sharing and full health insurance
- Posted: 19 October 2026
- Apply: open until filled (re-checked 20 November 2026)
Why this role matters
Quandela is one of Europe’s leading photonic quantum computing firms. This role works on its next step: linking spins with photons. It suits a postdoc ready to move into industry R&D with real ownership.
What the quantum optics scientist does
- Design, build and optimise optical experiments with spin-photon sources
- Set up optical control for spin initialisation, readout and manipulation
- Measure spin coherence, operation fidelity and entanglement quality
- Develop and validate photon-mediated spin-spin entanglement protocols
- Drive experiments from design to validation, and turn results into building blocks for multi-spin architectures
What Quandela is looking for
- A PhD in spin physics, quantum optics or a related field
- Hands-on experience with spin-based quantum systems: control, readout or coherence measurements
- Proven ability to design, optimise and troubleshoot complex quantum experiments on your own
- Strong understanding of quantum optics, spin coherence and measurement techniques
- The company mainly targets a PhD plus 4 or more years of postdoc or R&D work. Researchers finishing a substantial postdoc are also welcome
Nice to have
- Photon-mediated entanglement protocols and multi-spin architectures
- Semiconductor quantum emitters, quantum dots and spin-photon interfaces
- Advanced optical control, cryogenic platforms and fast electronics
- Experience bridging academic research and industrial R&D
Pay and location
The posting gives no salary. Listed benefits include profit-sharing, a company savings plan, full health insurance, half of public transport costs, and meal and sport subsidies. The job is on site at the IPVF campus in Palaiseau, in the Paris-Saclay research area. People management experience is not required.

How to prepare for this application
- Prepare a research talk: the process includes a technical presentation of your past work.
- Revise spin-photon interfaces: quantum dot charged excitons, optical selection rules and spin readout.
- Know entanglement schemes: heralded spin-spin entanglement and how photon distinguishability limits fidelity.
- Read about Quandela's SPOQC idea: spin-optical quantum computing, which mixes spins and photons.
- Show autonomy: bring an example where you set up and debugged an experiment largely on your own.
