NIST’s Superconducting Synapse May Be Missing Piece for ‘Artificial Brains’

January 26, 2018

Researchers at the National Institute of Standards and Technology (NIST) have built a superconducting switch that “learns” like a biological system and could

Projects and Programs

Qubits

The Qubits Project develops new geometries for superconducting quantum binary devices as fundamental building blocks for quantum computing.

Measurements of Point-Defect Chemistry in Complex Oxides

All inorganic materials contain point defects in the form of impurities, interstitials, or vacancies. Common imaging techniques fail to capture these defects

Amplifiers

To process quantum information it is important to have amplifiers with wide bandwidth, high dynamic range, and low noise.

Ab initio theoretical modeling for predicting structure and properties in advanced materials

We develop first-principles-based methods for prediction of atomic arrangements and properties in advanced materials and develop tools for the prediction and
