Project description DEENESFRITPL Enhancing light interactions with atomic ensembles Deterministic non-linear operations between single photons are at the heart of numerous quantum information protocols. Such operations involve strong interactions between photons and quantum emitters. Funded by the Marie Skłodowska-Curie Actions programme, the goal of the SinglePass project is to develop a novel platform to implement such operations by strongly coupling a photon with atomic ensembles in a single pass, that is, without the use of an optical cavity. Based on a promising photonic-crystal geometry and materials, this platform will offer superior figures of merit and scalability compared to free-space implementations, as well as tailored functionalities that are not possible to achieve in current physical interfaces. Show the project objective Hide the project objective Objective Deterministic nonlinear operations between single photons that are at the heart of numerous quantum information protocols require strong interactions between photons and quantum emitters. By combining cold atoms and slow-mode photonic-crystal waveguides, the goal of this project is to develop a novel platform to implement such operations by strongly coupling a photon with atomic ensembles in single pass, that is without the use of an optical cavity. Transverse optical confinement and slow group velocity are the key ingredients in this novel waveguide-QED approach, with applications in integrated quantum technologies, quantum non-linear optics and state engineering. This platform, based on a new and promising combination of photonic-crystal geometry (W1) and material (GaInP) will not only provide superior figures of merit and scalability than in free-space implementations, but also tailored functionalities not achievable in current physical interfaces. This project uniquely combines atomic physics, quantum optics and nanophotonics and will ideally prepare the applicant for a future career as an independent research group leader.
