Patents by Inventor Britton Louis Thomas Plourde

Britton Louis Thomas Plourde has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for circuit quantum electrodynamics measurement
    Patent number: 9692423
    Abstract: A system for quantum computation and a readout method using the same are provided. In some aspects, the system includes at least one qubit circuit coupled to a resonant cavity, wherein each of the at least one qubit circuit is described by multiple quantum states, and a controller configured to provide microwave irradiation to the resonant cavity such that a quantum state information of the at least one qubit circuit is transferred to a resonant cavity occupation. The system also includes a readout circuit, coupled to the resonant cavity, configured to receive signals corresponding to the resonant cavity occupation, and generate an output indicative of the quantum states of the at least one qubit circuit. Optionally, the system further includes at least one single flux quantum (“SFQ”) circuit coupled to the readout circuit and configured to receive the output therefrom.
