Photon-photon Interactions: giant Optical Nonlinearity EnginEering with Rydberg excitons – PIONEEReX

Submission summary

Photons are well-controlled information-carrying particles, but do not form many-body systems by lack of interactions. Can we artificially provide photons with strong long-range interactions? A positive answer would profoundly impact both quantum technologies and our understanding of complex many-body systems. I intend to import the successful techniques of cold Rydberg atoms into a solid-state setting to create on-chip optical nonlinearities at the single-photon level. This feat is of paramount importance for qubit manipulation and for the development of optical quantum simulators. For this I will exploit novel states of electron-hole pairs called Rydberg excitons, recently shown to possess the required properties. The end goal is a novel platform able to provide photons with interactions so large that they repel each other over microns. Such a platform will provide the groundwork for single-photon devices and photonic quantum simulation of exotic many-body states.
