Flux Quantum Electronics

Superconductive Circuits for Cryogenic Quantum Computing Quantum computing, and in particular cryogenic superconducting quantum computing with its demonstration of “ Quantum Supremacy”, has made tremendous progress over the past decade with many US companies playing primary roles in this
Johnson Noise Thermometer system

Noise Thermometry

Completed
The project has also created a quantum-based electronic temperature standard that uses the ACJVS in conjunction with measurement of the Johnson noise -- random electrical noise caused by thermal agitation in a conductor -- in resistors at arbitrary temperatures. This Johnson noise thermometry system
10 V programmable Josephson voltage standard (PJVS) and (right) PJVS cryopackaged chip, which are disseminated by the NIST standard reference instrument (SRI) program.

Quantum Voltage Project

Ongoing
Researchers in the Quantum Voltage Project develop and disseminate highly accurate instruments that exploit the quantum mechanical properties of superconductive devices known as Josephson junctions (JJs), as well as measurement techniques and best-practices for using these instruments. When a JJ is
