- About Quandela:
Quandela is a European deeptech scale-up developing modular, scalable and energy-efficient photonic and spin-optical quantum computers, accessible through the cloud and on-premises.
With over 140 employees, we develop our own hardware and software stack, from semiconductor quantum emitters and photonic processors to quantum control systems and algorithms.
Our ambition is to build large-scale, fault-tolerant quantum computers, combining quantum dot technologies, scalable spin-photon interfaces and distributed entanglement within future Spin-Optical Quantum Computing (SPOQC) architectures.
- About this position:
You will join Quandela's Semiconductor Optics Team, bringing together expertise in quantum optics, spin physics, semiconductor technologies and quantum information.
Your focus will be to contribute to spin-based quantum experiments, develop optical control and characterization techniques, and support the demonstration of photon-mediated spin-spin entanglement for future quantum computing architectures.
We are looking for an experimental scientist with a strong foundation in quantum optics or spin physics, particularly through hands-on work with quantum emitters, optical spectroscopy or single-photon experiments.
With several experimental building blocks still under development, you'll have the opportunity to explore challenging scientific questions, develop your expertise alongside experienced scientists and engineers, and progressively take ownership of experimental activities contributing directly to our technology roadmap.
- What you'll do:
Spin-based quantum experiments:
Develop optical experiments on spin-photon quantum systems.
Operate and improve setups for individual quantum emitters.
Explore optical spin initialization, control and readout.
Measure spin coherence, operation fidelity and photon quality.
Perform optical spectroscopy and single-photon measurements.
Experimental development and scientific investigation:
Plan experiments, acquire data and interpret results.
Troubleshoot optical setups and improve measurement stability.
Gradually own experiments and propose scientific approaches.
Technology development and collaboration:
Study photon interference and spin-spin entanglement protocols.
Connect experimental results with theory and device teams.
Improve reproducibility, robustness and system performance.
Help turn experimental results into multi-spin demonstrators.
- How You Will Grow:
During your first 3 months:
You will become familiar with Quandela's experimental platforms, optical spectroscopy and spin-control techniques, contributing to ongoing measurements and experimental activities alongside the team.
Within 6 months:
You will take ownership of defined experimental tasks, contribute to setup optimization and protocol development, and actively participate in theory-to-experiment feedback loops.
Within 1 year:
You will independently drive specific experimental investigations, contribute to distributed entanglement demonstrations and help advance future spin-based architectures.
