Photonic Quantum Matter
Abstract
In our MURI "Photonic Quantum Matter," we investigated various aspects of strong light-matter interaction which has led to interesting experimental and theoretical results. To highlight a few examples, (1) we demonstrated topological sources of light that can generate photon-pairs with remarkable insensitivity to fabrication disorders using a silicon photonic platform, (2) we demonstrated the realization of Landau-level in twisted resonators and we created two-photon Laughlin states, by using a strongly interacting topological fluid of Rydberg polaritons in lowest Landau level as a photon collider, (3) we demonstrated the fabrication and characterization of a superconducting metamaterial waveguide in which a large photonic bandgap is present with topological properties, (4) we demonstrated the first topological quantum optics interface: quantum emitters coupled to topological edges of a photonic crystal, (5) we reported the experimental realization of memory-enhanced quantum communication based on silicon-vacancy (SiV) color centers coupled to diamond nanodevices, (6) we demonstrated three-photon bound state in Rydberg medium, and (7) motivated by these experimental demonstrations, we theoretically investigated whether quantum-optical control techniques could pave the way for radically new directions to prepare, manipulate, and detect correlated electron systems. Specifically, this includes an optical drive or a passive cavity, showing the possibility of creating driven topological states, magnetism, and signatures of enhanced superconductivity, and suggesting new routes for engineering other correlated states such as fractional quantum Hall states. Overall, these observations and theoretical efforts opened a passage to realizing robust single-photon switches and all optical quantum logic gates, with built-in protection, and to exploring novel quantum many-body phenomena with strongly interacting photons.
