Together with a PhD student, the post-doc will design and operate the experimental set-up to tune the spectroscopic properties of the QD, carry out resonant micro-photoluminescence and perform the entanglement measurements. This work will be done in very close collaboration with a PhD student and a post-doc of the CEA-IRIG team that will be in charge of the design and fabrication of the samples.

A two-year post-doctoral position is available at Institut Néel (Grenoble, France) in the Quantum Optics group led by Jean-Philippe Poizat. This position is part of the project A bright source of Indistinguishable Polarization-entangled On-Demand photon pairs obtained together with the team of Julien Claudon, and Jean-Michel Gérard at CEA-IRIG (Grenoble, France), from the Agence Nationale de la Recherche (ANR).

The goal of this project is to use a single semiconductor quantum dot (QD) embedded in a photonic waveguide to produce polarization entangled photon pairs with a very high quantum efficiency. The specificity of this project is that we will use strain and electrostatic fields to tune the properties of the QD and produce a device satisfying all the requirements for a realistic implementation in a quantum communication set-up.

Institut Néel is one of the largest French national research institutes in condensed matter physics. Grenoble features a unique scientific, industrial and cultural ecosystem. It offers one of Europe's largest high-tech center. Grenoble has been identified as one of the three French Quantum Hubs together with Paris and Saclay. It benefits from an exceptional environment at the heart of the French Alps.

The candidate must have a solid background in experimental semiconductor optics and/or quantum optics. She/he must be able to supervise a PhD student and to conduct an experimental project with large autonomy. Work with Institut Néel technical staff and with our CEA-IRIG collaborators will require a strong team spirit.
