In recent years superconducting circuits have emerged as a promising platform for quantum computation and quantum simulation. One of the driving forces behind this progress is the ability to fabricate relatively low-disorder, low-loss circuits with a high-degree of control over many of the circuit parameters, both in fabrication and in-situ. The field, broadly called circuit quantum electrodynamics (cQED), has become one of the cleanest and most flexible platforms for studying strong interactions between light and matter, in addition to allowing the necessary operations for quantum computation.
In this talk, I will describe my PhD work exploring large-scale, superconducting circuit lattices to investigate nonequilibrium quantum simulation. First, I will describe my experimental work on a 72-site one-dimensional array of coplanar waveguide cavities and transmon qubits where we observed a novel dissipative phase transition. Next, I will describe our work on a hyperbolic array of coplanar waveguide cavities that exhibited a gapped flatband model which has important consequences for many-body physics. Afterward, I will describe our mathematical understanding of the origin of flatbands in these systems and how to exploit ideas from graph theory to maximize the gaps between these flat bands and the rest of the spectrum. Finally, I will broadly describe some of the current limitations of superconducting devices before concluding with future plans to further improve the capabilities and performance of near-term quantum processors made from superconducting circuits.
