Practical realisation of the kelvin by Johnson noise thermometry

Author(s)
Horst Rogalla, D Rod White, Jifeng Qu, Samuel P. Benz, Christof Gaiser, Weston L. Tew, Nathan Flowers-Jacobs, Kevin J. Coakley, Alessio Polarollo, Chiharu Urano
Johnson noise thermometry (JNT) is a purely electronic method of thermodynamic thermometry. In primary JNT, the temperature is inferred from a comparison of the

Quantum-Based Microwave Modulated Waveforms

Author(s)
Akim Babenko, Nathan Flowers-Jacobs, Anna Fox, Paul Dresselhaus, Zoya Popovic, Samuel P. Benz
This paper presents a superconducting voltage source that generates microwave modulated waveforms with quantum-based stability. The voltage source - an RF

Josephson Voltage Standard

NIST Inventors
Samuel P. Benz , Paul Dresselhaus , Alain Rufenacht , Nathan Flowers-Jacobs and Anna Fox
A Josephson voltage standard includes: electrical conductors that receive bias currents and radiofrequency biases; a first Josephson junction array that: includes a first Josephson junction and produces a first voltage reference from the first bias current and the third bias current; a second

Superconducting Waveform Synthesizer

NIST Inventors
Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins
A superconducting waveform synthesizer produces an arbitrary waveform and includes an encoder that produces a bitstream; a pattern generator that produces a current bias pulse from the bitstream; a Josephson junction that produces a quantized output pulse from the current bias pulse; and a converter
