System And Mathod For Parameter Multiplexed Gradient Descent

NIST Inventors
Adam McCaughan , Sonia Buckley and Andrew Dienstfrey
Embodiments of the present invention relate to systems and model-free methods for perturbing neural network hardware parameters and measure the neural network response that are implemented natively within the neural network hardware and without requiring a knowledge of the internal structure of the
Diagram showing the circuit for resetting the Spectral Power Distribution (SPD) after the Light Emitting Diode (LED) has emitted a photonic pulse.

Superconducting Opto-Electronic Transmitter Circuit

NIST Inventors
Sonia Buckley and Adam McCaughan
This invention describes a family of circuits that receive an input current or voltage pulse when a superconducting element has been driven above threshold, producing an amplified current or voltage pulse to drive a light source, and reset to the resting state after light has been generated.

Josephson Junction Circuits For Single-Photon Optoelectronic Neurons And Synapses

NIST Inventors
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
Line drawing of the thermal impedance amplifier

Thermal Impedance Amplifier

NIST Inventors
Adam McCaughan , Varun Verma and Sonia Buckley
A thermal impedance amplifier includes: a resistive layer including: a resistance member; a first electrode in electrical communication with the resistance member; and a second electrode in electrical communication with the resistance member; a switch layer opposing the resistive layer and including
