Compact Low-power Cryo-Cooling Systems For Superconducting Elements

NIST Inventors
Joel Ullom , Sae Woo Nam 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

Josephson Junction Circuits For Single-Photon Optoelectronic Neurons And Synapses

NIST Inventors
Jeff Shainline , Adam McCaughan , Sae Woo Nam 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

Neuromimetic Circuit

NIST Inventors
Sae Woo Nam , 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

Thermal Impedance Amplifier

NIST Inventors
Adam McCaughan , Varun Verma , Sonia Buckley and Sae Woo Nam
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
