  • Josephson junction circuits for single-photon optoelectronic neurons and synapses
    Patent number: 11283002
    Abstract: A primary single photon optoelectronic neuron includes a photonic synaptic input waveguide; an optoelectronic synapse; a synapto-dendritic electrical connection in communication with the optoelectronic synapse; an electronic dendrite in communication with the synapto-dendritic electrical connection; a dendrite-neuronal electrical interface in communication with the electronic dendrite; an integrator in communication with the dendrite-neuronal electrical interface; a superconducting wire in communication with the integrator; an axon hillock electronic-to-photonic transducer in communication with the superconducting wire; and an axonic waveguide in communication with the axon hillock electronic-to-photonic transducer and that receives the axonic photonic signal.
    Type: Grant
