Realization of a Quantum Topological Photon Pump
Qianao Yue, Bernardo Barrera, Martin Ritter +4
Topological pumps transfer charge or energy at quantized rates determined solely by band topology, independent of the details of the control fields. Photon pumps operating on this…
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…
Autonomous Stabilization of Floquet States Using Static Dissipation
Martin Ritter, David M. Long, Qianao Yue +2
Floquet engineering, in which the properties of a quantum system are modified through the application of strong periodic drives, is an indispensable tool in atomic and condensed ma…
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…
Generalized geometric speed limits for quantum observables
Jacob Bringewatt, Zach Steffen, Martin A. Ritter +6
Leveraging quantum information geometry, we derive generalized quantum speed limits on the rate of change of the expectation values of observables. These bounds subsume and, for Hi…
