In a Nature Perspective, we highlight a paradigm based on controlling lightâ€“matter interactions that provides a way to manipulate and synthesize strongly correlated quantum matter. Photonmediated superconductivity, cavity fractional quantum Hall physics and optically driven topological phenomena in low dimensions are among the frontiers discussed in this Perspective.

Our group aims to theoretically and experimentally investigate various quantum properties of lightmatter interaction for applications in future optoelectronic devices, quantum information processing, and sensing. Moreover, we explore associated fundamental phenomena, such as manybody physics, that could emerge in such physical systems. Our research is at the interface of quantum optics, condensed matter physics, quantum information sciences, and more recently, machine learning.

Recent progress on quantum random sampling protocols such as random circuit sampling (interacting) and boson sampling (noninteracting) demonstrate an advantage of quantum information processing. Is there an intermediately interacting regime where the random sampling becomes intractable in a classical setting and becomes feasible on a quantum device? We found that such an intermediately interacting regime could be feasibly utilized by a generalization of current boson sampling protocols.
