Quandela is a European scale-up that provides photonic quantum computers that are modular, scalable, energy-efficient, and accessible both on the cloud and on-premise.

Our team of 140 employees specialises in the development of both software and hardware solutions for a variety of quantum applications. We offer a wide range of services: from building the brightest single-photon sources, to designing algorithms for quantum computers, to providing cloud quantum computing access.

Quandela plays a pivotal role as a strategic partner in the quantum transformation of industrial sectors such as energy, finance, pharmaceuticals, and transportation. We are also esteemed collaborators within the academic and research community.

About this position:

You will join Quandela's Semiconductor Research & Development Optics division, based in Palaiseau, close to the C2N and IPVF research hubs.
This division studies, engineers, and optimizes semiconductor-based quantum emitters - the core light sources enabling photonic quantum computing.

Within this division, the Optical Drive team develops advanced optical excitation schemes for single-photon sources.

The team explores approaches such as chirped-pulse control and pulse shaping to improve brightness, purity, and indistinguishability - enabling polarization-encoded cluster states and advancing Quandela's roadmap toward fault-tolerant quantum computing.

We are opening a Research Scientist position to strengthen this effort - developing and validating new excitation schemes for semiconductor-based single-photon sources, bridging fundamental optics and applied photonics.

Why This Role Matters?

Your work will turn quantum optics research into photonic quantum computing capability.

You'll help bridge the gap between fundamental experiments and operational technology - ensuring that tomorrow's quantum computers are powered by brighter, purer, and more reliable single-photon sources, while pushing the limits of semiconductor quantum emitters toward tangible hardware impact.

This role is about transforming scientific insight into hardware reality - a chance to contribute where research meets industry, and where every experiment brings us closer to scalable, fault-tolerant photonic systems.
