The Superconductive Electronics Group at NIST is developing advanced quantum-based measurement technologies using superconducting materials and Josephson junctions. Their work focuses on creating precise measurement standards for voltage, waveform synthesis, and thermometry that can be used in high-performance applications like energy-efficient computing and RF communications.
The group is working on two main projects: Quantum Voltage and Noise Thermometry, which aim to establish reliable standards for precise electrical measurements, and Flux Quantum Electronics, which focuses on developing cryogenic superconducting circuits for advanced computing and communications.
The fundamental standards for voltage measurements are based on the Josephson Effect, a quantum phenomenon that allows precise voltage measurements at the quantum level. NIST’s work in this area has the potential to revolutionize electrical metrology and enable more accurate and efficient quantum-based technologies.
