Robust cavity metrology beyond the limits of Pound-Drever-Hall
Ibukunoluwa Adisa, Won Chan Lee, Yanqin Huang +3
Precise measurement of the resonance frequencies of microwave and optical cavities is a foundational capability across quantum technologies. One of the highest-performance methods…
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…
Anomalous Boundary Modes in a Floquet Hyperbolic System
Ali Fahimniya, Hossein Dehghani, Alicia J. Kollár +1
We construct an anomalous Floquet topological phase on a negatively curved hyperbolic lattice. The model is a tight-binding Hamiltonian with a periodically repeated four-color edge…
Dissipative Stabilization of Floquet-Engineered Many-Body Order
Shreyas Raman, Robin Schäfer, Robin Schafer +3
Floquet driving underlies Hamiltonian and gate engineering, and produces dynamical orders with no equilibrium counterpart. These phenomena are, however, transient in well-isolated…
The Pound-Drever-Hall Method for Superconducting-Qubit Readout
Ibukunoluwa Adisa, Won Chan Lee, Kevin C. Cox +1
Scaling quantum computers to large sizes requires the implementation of many parallel qubit readouts. Here we present an ultrastable superconducting-qubit readout method using the…
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…
