  • Flux control of qubit under resonant excitation
    Patent number: 10650319
    Abstract: Systems and methods are provided for flux control of a qubit. A quantum system includes a microwave transmitter configured to provide a continuous microwave tone, and a qubit configured such that a portion of an energy spectrum of the qubit is responsive to an applied flux. The qubit also has an inductive element responsive to the continuous microwave tone to produce a Rabi oscillation within the qubit. A flux source is configured to apply a flux to the qubit.
    Type: Grant
    Filed: February 6, 2015
    Date of Patent: May 12, 2020
    Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATION
