Time-Dependent Hamiltonian Reconstruction using Continuous Weak Measurements
Karthik Siva, Gerwin Koolstra, John Steinmetz +9
Reconstructing the Hamiltonian of a quantum system is an essential task for characterizing and certifying quantum processors and simulators. Existing techniques either rely on proj…
Localization and reduction of superconducting quantum coherent circuit losses
M. Virginia P. Altoé, Archan Banerjee, Cassidy Berk +16
Quantum sensing and computation can be realized with superconducting microwave circuits. Qubits are engineered quantum systems of capacitors and inductors with non-linear Josephson…
Quantum metamaterial for nondestructive microwave photon counting
Arne L. Grimsmo, Baptiste Royer, John Mark Kreikebaum +4
Detecting traveling photons is an essential primitive for many quantum information processing tasks. We introduce a single-photon detector design operating in the microwave domain,…
Quantum Information Scrambling in a Superconducting Qutrit Processor
M. S. Blok, V. V. Ramasesh, T. Schuster +7
The theory of quantum information provides a common language which links disciplines ranging from cosmology to condensed-matter physics. For example, the delocalization of quantum…
Improving wafer-scale Josephson junction resistance variation in superconducting quantum coherent circuits
J. M. Kreikebaum, K. P. O'Brien, A. Morvan +1
Quantum bits, or qubits, are an example of coherent circuits envisioned for next-generation computers and detectors. A robust superconducting qubit with a coherent lifetime of (…
High-efficiency measurement of an artificial atom embedded in a parametric amplifier
A. Eddins, J. M. Kreikebaum, D. M. Toyli +7
A crucial limit to measurement efficiencies of superconducting circuits comes from losses involved when coupling to an external quantum amplifier. Here, we realize a device circumv…
