JOSEPHSON JUNCTION CIRCUITS FOR SINGLE-PHOTON OPTOELECTRONIC NEURONS AND SYNAPSES

NIST Inventors
Jeff Shainline , Adam McCaughan , Sae Woo Nam and Manuel Castellanos Beltran
patent description We recently invented and patented a new type of hardware for neuromorphic computing (Phys. Rev. Applied, 7, 034013 (2017) (attached to email). The key ideas are to use integrated photonic devices for massive connectivity nd superconducting electronics for efficient memory and

Superconducting Waveform Synthesizer

NIST Inventors
Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins
Patent Description NIST has 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
