Multimode Strong-Coupling Processes in Circuit QED Lattices
Won Chan Lee, Ali Fahimniya, Kellen O'Brien +5
Circuit QED systems provide an ideal platform for exploring the strong-coupling regime of multimode cavity QED. Here we present two new phenomena from multimode strong coupling: a…
In-situ Characterization of Light-Matter Coupling in Multimode Circuit-QED Systems
Kellen O'Brien, Won Chan Lee, Alexandra Behne +5
Multimode cavity-QED systems can be leveraged to explore a wide range of physical phenomena; however, a complex multimode environment makes systematic characterization of light-mat…
A Circuit-QED Lattice System with Flexible Connectivity and Gapped Flat Bands for Photon-Mediated Spin Models
Kellen O'Brien, Maya Amouzegar, Won Chan Lee +2
Quantum spin models are ubiquitous in solid-state physics, but classical simulation of them remains extremely challenging. Experimental testbed systems with a variety of spin-spin…
A strong-driving toolkit for topological Floquet energy pumps with superconducting circuits
Martin Ritter, David M. Long, Qianao Yue +3
Topological Floquet energy pumps -- which use periodic driving to create a topologically protected quantized energy current -- have been proposed and studied theoretically, but hav…
