Patents by Inventor Brenden Butters

Brenden Butters 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).

  • Superconducting nanowire-based programmable processor
    Patent number: 11200947
    Abstract: Apparatus and methods relating to programmable superconducting cells are described. A programmable superconducting cell can be formed from a superconducting current loop having at least two terminals connected to the loop. The current loop and terminals can be formed from a single layer of superconducting material. The programmable superconducting cell can be incorporated into a crossbar architecture to form a high-speed vector-matrix multiplying processor for deep neural network computations.
    Type: Grant
    Filed: February 4, 2019
    Date of Patent: December 14, 2021
    Assignee: Massachusetts Institute of Technology
    Inventors: Karl K. Berggren, Oguzhan Murat Onen, Brenden Butters, Emily Toomey
  • Single-photon single-flux coupled detectors
    Patent number: 11024790
    Abstract: A device that is a combination of a superconducting nanowire single-photon detector and a superconducting multi-level memory. These devices can be used to count a number of photons impinging on the device through single-photon to single-flux conversion. Electrical characterization of the device demonstrates single-flux quantum (SFQ) separated states. Optical measurements using attenuated laser pulses with different mean photon number, pulse energies and repetition rates are shown to differentiate single-photon detection from other possible phenomena, such as multiphoton detection and thermal activation. Array devices and methods are also discussed.
