System And Method For Parameter Multiplexed Gradient Descent

NIST Inventors
Adam McCaughan , Sonia Buckley and Andrew Dienstfrey
Parameter multiplexed gradient descent (PMGD) is a machine learning training method designed to easily train emergent non-volatile memory and neuromorphic hardware platforms.

Compact Low-power Cryo-Cooling Systems For Superconducting Elements

NIST Inventors
Joel Ullom and Vincent Kotsubo
A compact, low power cryo-cooler for cryogenic systems capable of cooling gas to at least as low as 2.5 K. The cryo-cooler has a room temperature compressor followed by filtration. Within the cryostat, four counterflow heat exchangers precool the incoming high-pressure gas using the outflowing low

Ultra-Sensitive Camera for Clearer Images in Medicine, Space, and Security

NIST Inventors
Adam McCaughan
This invention introduces a thermally coupled imager designed to detect and track single photons with high accuracy. It integrates a thermal detection layer with photon-sensitive pixels to enhance imaging precision. The system improves time and position-sensitive imaging, making it ideal for

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
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

Neuromimetic Circuit

NIST Inventors
Jeff Shainline and Sonia Buckley
Optoelectronic neural networks comprise a system of interconnected processing units (neurons) interconnected by integrated photonic waveguides. The processing units receive photonic signals from other units. Each unit sums the received signals on a waveguide-integrated photon detector, and when the
