Post-doc: spin-photon interfaces for quantum information

Deadline 22/04/2026

Starting 01/07/2026

Contrat type: Post-doc

Duration: 2 years

Keywords: spin-photon, quantum information, qubit, photon-photon logic gates, entanglement, Raman cooling

This work takes place within the GOSS group of the Photonics Department in C2N, where a strong activity in quantum optics and nanophotonics is developed in a collaborative fashion, on a diversity of research themes (e.g. light-matter interfaces, solid-state physics in semiconductors, polariton quantum fluids, nanophononics and ultrafast nano-acoustics...)

Beyond the experiments on fundamental physics, the activities of the recruiting team include an activity towards potential industrial transfers (self-calibrating instruments for polarization control), and an activity on theory (simulations of cavity-QED devices), which both represent assets for the present post-doctoral position.

The offered position is funded by the OQuLus project, within the PEPR Quantique. The OQuLus consortium gathers expertise from french groups with internationally-recognized results, going from semiconductor physics to integrated optics. It aims at realizing two prototypes of photonic quantum computers exploiting the encoding of information on quantum light, either usiing "discrete variables" (photon number superpositions) or "continuous variables" (field quadratures).

The main missions of the recruited post-doctoral researcher will be:

• To develop experiments using the spin-photon interfaces as receivers of incoming photons, for the implementation of spin-photon and photon-photon logic gates.
• To increase the spin qubit coherence by reducing the magnetic fluctuations of the environment, through techniques analogous to Raman cooling.
• To demonstrate new forms of entanglement, through which a spin qubit is used to successively entangle several incoming photons
