Title: Cavity QED from Manybody Physics to Transduction

Abstract: In this talk, I will describe recent developments in the Simon/Schuster collaboration, where we are harnessing cavity quantum electrodynamics for both manybody physics and quantum information. I will begin with an overview of our photonic quantum materials efforts, highlighting the analogy between photons in a lattice of cavities (or family of cavity modes) and electrons in solids. I will then focus in on our explorations of Hubbard physics in a quantum circuit, where we have demonstrated reservoir engineering approaches to stabilizing incompressible solids, and more recently, disorder-assisted adiabatic approaches to preparation of compressible fluids and even cat states of fluids. Finally I will change gears and talk briefly about interfacing superconducting and optical cavities using Rydberg atoms, where we have just demonstrated a quantum limited mmwave-to-optical transducer with >50% transduction efficiency, 100’s of kHz of bandwidth, and less than one noise photon.
