In recent years, dielectric metasurfaces have transformed optical imaging by replacing complex combinations of optical elements with structured surfaces that are thin and highly efficient. This project aims to design optimized metasurfaces to distribute different photon states among multiple users while minimizing the number of optical components needed for quantum network development. The core concept is that metasurfaces, with their numerous scattering channels, can serve as the foundation for compact quantum networks enabling multiparty communication.

Throughout the project, students will develop a unique skill set in advanced photonics, quantum information, and machine learning-based inverse design, offering strong foundations for future career prospects. The project will be carried out in collaboration with the Atlantis group at INRIA, University of the Côte d’Azur, France, who will provide guidance on the inverse design of metasurfaces. The PhD student may also spend time at INRIA during their thesis work.
