Photon-Mediated Interactions in Quasi-1D Lattices of Coplanar Waveguide Resonators

Circuit quantum electrodynamics (circuit QED) is quickly becoming one of the main platforms for quantum simulation and computation. One of its notable advantages is its ability to facilitate the study of new regimes of light-matter interactions. This is achieved due to the native strong coupling between superconducting qubits and microwave resonators, and the ability to lithographically define a large variety of resonant microwave structures, for example photonic crystals. Such geometries allow the implementation of novel forms of photon-mediated qubit-qubit interaction, and studies of many-body physics. In this talk, I will introduce how coplanar waveguide (CPW) lattices can be used to create engineered photon-mediated interactions. I will present preliminary data characterizing photon-mediated interactions between tunable transmon qubits in a quasi-1D lattice of CPW resonators with unconventional bands, such as gapped and ungapped flat bands.
