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…
Dissipative Stabilization of Floquet-Engineered Many-Body Order
Shreyas Raman, Robin Schäfer, Alicia J. Kollar +1
Floquet driving underlies Hamiltonian and gate engineering, and produces dynamical orders with no equilibrium counterpart. These phenomena are, however, transient in well-isolated…
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…
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…
Realization of pure gyration in an on-chip superconducting microwave device
Zhiyin Tu, Violet Workman, Gaurav Bahl +1
Synthetic materials that emulate tight-binding Hamiltonians have enabled a wide range of advances in topological and non-Hermitian physics. A crucial requirement in such systems is…
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…
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…
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…
Efficiently verifiable quantum advantage on near-term analog quantum simulators
Zhenning Liu, Dhruv Devulapalli, Dominik Hangleiter +4
Existing schemes for demonstrating quantum computational advantage are subject to various practical restrictions, including the hardness of verification and challenges in experimen…
Extended Josephson junction qubit system
Andrey Grankin, Alicia J. Kollár, Mohammad Hafezi
Circuit quantum electrodynamics (QED) has emerged as a promising platform for implementing quantum computation and simulation. Typically, junctions in these systems are of a suffic…
Fault-tolerant hyperbolic Floquet quantum error correcting codes
Ali Fahimniya, Hossein Dehghani, Kishor Bharti +4
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits r…
