Chiral cavity quantum electrodynamics in a 3D microwave lattice coupled to a transmon qubit (Part 2)

ORAL

Abstract

We describe work combining a single transmon with this topological lattice, achieving, for the first time, a platform for chiral cavity quantum electrodynamics. We show strong coupling between the qubit and the topological lattice. Using the qubit we prepare arbitrary quantum states of the lattice edge modes and we can non-destructively measure their photon occupation. Finally, we describe a path towards coupling multiple transmons to edge sites of the lattice, enabling exploration of photon-photon interactions in a topological band structure.
