Model for l/f Flux Noise in SQUIDs and Qubits
Roger H. Koch, David P. DiVincenzo, John Clarke
We propose a model for 1/f flux noise in superconducting devices (f is frequency). The noise is generated by the magnetic moments of electrons in defect states which they occupy fo…
Low-bandwidth control scheme for an oscillator stabilized Josephson qubit
R. H. Koch, J. R. Rozen, G. A. Keefe +4
We introduce a new Josephson junction circuit for which quantum operations are realized by low-bandwidth, nearly adiabatic magnetic-flux pulses. Coupling to the fundamental mode of…
Asymmetry and decoherence in a double-layer persistent-current qubit
Guido Burkard, David P. DiVincenzo, P. Bertet +2
Superconducting circuits fabricated using the widely used shadow evaporation technique can contain unintended junctions which change their quantum dynamics. We discuss a supercondu…
