Josephson Junction Circuits For Single-Photon Optoelectronic Neurons And Synapses

NIST Inventors

Jeff Shainline , Adam McCaughan and Manuel Castellanos Beltran

Single-photon optoelectronic neurons convert the optical signals of single photons to the electrical domain where summing and thresholding operations are performed. In these circuits, the photonic signals are converted to an electronic signal using a superconducting single-photon detector in

Superconducting Waveform Synthesizer

NIST Inventors

Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins

A superconducting waveform synthesizer produces an arbitrary waveform and includes an encoder that produces a bitstream; a pattern generator that produces a current bias pulse from the bitstream; a Josephson junction that produces a quantized output pulse from the current bias pulse; and a converter
