Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Origin and Suppression of Magnetic Flux Noise
P. Kumar, S. Sendelbach, M. A. Beck +7
Magnetic flux noise is a dominant source of dephasing and energy relaxation in superconducting qubits. The noise power spectral density varies with frequency as with $α\sim…
Coherent Josephson phase qubit with a single crystal silicon capacitor
U. Patel, Y. Gao, D. Hover +3
We have incorporated a single crystal silicon shunt capacitor into a Josephson phase qubit. The capacitor is derived from a commercial silicon-on-insulator wafer. Bosch reactive io…
Superconducting Low-Inductance Undulatory Galvanometer Microwave Amplifier
D. Hover, Y. -F. Chen, G. J. Ribeill +3
We describe a microwave amplifier based on the Superconducting Low-inductance Undulatory Galvanometer (SLUG). The SLUG is embedded in a microstrip resonator, and the signal current…
Microwave Photon Counter Based on Josephson Junctions
Y. -F. Chen, D. Hover, S. Sendelbach +5
We describe a microwave photon counter based on the current-biased Josephson junction. The junction is tuned to absorb single microwave photons from the incident field, after which…
Calculations for Magnetism in SQUIDs at Millikelvin Temperatures
S. Sendelbach, D. Hover, A. Kittel +3
Here we present details of a calculation that allows us to extract a surface density of unpaired spins from flux vs. temperature experiments performed on field-cooled dc Supercondu…
