PhD in Quantum photonics with novel nanomaterials

Institut de Recherche de Chimie Paris – Université PSL – Chimie ParisTech – CNRS
11 rue Pierre et Marie Curie, 75005 Paris

The Crystals and Quantum State Dynamics group seeks motivated and talented PhD students to join our team developing novel nanomaterials for quantum computing and quantum communication applications. We use nanostructured crystals to realize a solid-state quantum interface between spin and photonic degrees of freedom, a great challenge for future quantum technologies. Rare-earth ion-doped (REI) crystals provide long spin and optical coherence times and are promising for realizing quantum memories, quantum sensors, and single photon sources; however, their nanofabrication is in the early technological stage and needs a significant boost. The project is aimed to develop novel REI materials based on nanoparticles and thin films, preserving the coherent properties of REIs and enabling their further integration with a broader range of nanophotonic platforms.

The project combines low-temperature physics using dilution refrigerators, fabrication of novel nanomaterials, high-resolution optical and spin spectroscopy, and design and fabrication of nanophotonic devices in collaboration with French and international research groups.

The PhD student's tasks will include the following:
- Learning about using solid-state spin ensembles for quantum information applications ;
- Acquiring the fabrication skills to develop nanomaterials based on nanoparticles and thin films (atomic layer deposition and chemical vapour deposition, spin coating etc.);
- Studying developed samples using optical spectroscopic techniques at cryogenic temperatures;
- Designing and fabricating novel nanophotonic interfaces using clean-room fabrication/ processing (lithography, reactive ion etching etc.).

We are looking for candidates with a background in Nanoscience, Applied Physics, and Optical or Electrical Engineering. Applicants are expected to have:
- Background in optics, solid-state physics, or optoelectronics, including experimental skills ;
- Basic knowledge of quantum physics and quantum information;
- Interest in experimental work and nanofabrication (previous experience working in chemical labs/cleanrooms is a plus);
- Ability to work independently and in daily collaboration with the research team.

Our group ( is developing a new set of nanomaterials based on rare earth dopants to control optical and spin non-classical states. The combination of structural characterization and optical spectroscopy allows us to synthesize nanostructures with low perturbations to the quantum states.

The group is a part of the Material for Photonics and Opto-Electronics (MPOE) team of the Institut de Recherche de Chimie Paris, located in Paris.

We offer creative and stimulating working conditions in a dynamic, international research environment. Our research facilities include modern optical laboratories and fabrication facilities to synthesize nanomaterials.
