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
We have invented a pulse quantizer that uses arrays of one or more Josephson junctions to create a pulse voltage output that is immune to differential pulse timing shifts. When the output pulse patterns are used to encode a waveform, for example, the waveform will be free from pulse timing shifts
