Phonon-Mediated Quasiparticle Poisoning of Superconducting Microwave Resonators
U. Patel, Ivan V. Pechenezhskiy, B. L. T. Plourde +2
Nonequilibrium quasiparticles represent a significant source of decoherence in superconducting quantum circuits. Here we investigate the mechanism of quasiparticle poisoning in dev…
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…
Magnetoresistance Oscillations in Granular Superconducting Niobium Nitride Nanowires
U. Patel, Z. L. Xiao, A. Gurevich +5
We report on magnetoresistance oscillations in superconducting NbNx nanowires synthesized through ammonia gas annealing of NbSe3 precursor nanostructures. Even though the transvers…
Multi-gap nodeless superconductivity in iron selenide FeSe: evident from quasiparticle heat transport
J. K. Dong, T. Y. Guan, S. Y. Zhou +6
The in-plane thermal conductivity of the iron selenide superconductor FeSe ( = 8.8 K) were measured down to 120 mK and up to 14.5 T (). In zero fiel…
Growth and Superconductivity of FeSex Crystals
U. Patel, J. Hua, S. H. Yu +7
Iron selenide (FeSex) crystals with lateral dimensions up to millimeters were grown via a vapor self-transport method. The crystals consist of the dominant alpha - phase with trace…
