Quantum Optics Scientist - Spin-Based Quantum Systems

Quantum Optics Scientist - Spin-Based Quantum Systems
Quandela
Palaiseau, France
About this position:
You will join Quandela's Semiconductor Optics Team, a multidisciplinary group combining expertise in quantum optics, spin physics, semiconductor technologies, electronics and quantum information.
The team develops the building blocks required for future hybrid spin-photon quantum computing architectures, bridging quantum science, technology development and product-oriented demonstrators.
In this role, you will contribute to the development and validation of photon-mediated spin–spin entanglement protocols while improving the performance of spin-based quantum systems.
Current challenges include enhancing spin coherence against decoherence, validating high-fidelity spin qubit operations, developing advanced optical control techniques and strengthening theory-to-experiment feedback loops for future multi-spin architectures.
Beyond the scientific challenges, you will contribute to building demonstrators that will directly become part of future quantum computing platforms. Success in this role relies on combining scientific rigor, collaboration across Quandelas production and research departments.
What you'll do:
As a Quantum Optics Scientist, you will contribute to the development of spin-based quantum technologies supporting Quandela's longterm quantum computing roadmap.
Your work will include:
Design, develop and improve optical experiments involving spin-photon sources;
Develop and implement optical control schemes for spin initialization, readout and characterization;
Characterize key spin properties including coherence, operation fidelity and entanglement quality;
Collaborate with theory, electronics and semiconductor technology teams to improve device performance and accelerate experimental progress;
Contributing to the development and validation of photon-mediated spin–spin entanglement protocols and future multi-spin architectures;
Validate and translate scientific advances into robust technological building blocks for future hybrid quantum computing systems.
Requirements:
Ideal Profile:
PhD in Spin Physics, Quantum Optics, Spin-Photon interfaces in the solid state or related fields;
Hands-on experimental research experience in spin physics, quantum optics, semiconductor quantum systems, quantum emitters, or closely related areas;
Experience developing, optimizing, and troubleshooting experimental quantum systems in a laboratory environment;
Familiarity with techniques such as spincontrol, optical manipulation, coherence measurements, single-photon characterization or related experimental methods;
Comfortable working alongside physicists, engineers and theorists in a multidisciplinary environment;
Curious, collaborative and motivated by challenging scientific and technological problems.
Bonus Points:
Experience in one or more of the following areas is highly appreciated:
Spin-photon interfaces;
Semiconductor quantum emitters and quantum dots;
Ultrafast optics and advanced optical control;
Fast control electronics, cryogenic experimental platforms, and advanced laboratory instrumentation.
