Superconducting metamaterials for waveguide quantum electrodynamics
Abstract
Metamaterials remain relatively unexplored in quantum optics. Here, the authors couple a transmon qubit to a superconducting metamaterial with a deep sub-wavelength lattice constant and probe the coherent and dissipative dynamics of the system by measuring the Lamb shift and radiative lifetime of the qubit.
