NIST researchers have successfully installed a new quantum voltage standard, the Programmable Josephson Voltage Standard (PJVS), at Spain’s National Institute of Aerospace Technology (INTA). This marks the first deployment of NIST’s fully automated, cryogen-free PJVS Standard Reference Instrument (SRI) 6000 system in Europe.
The new PJVS system, which replaces INTA’s conventional Josephson voltage standard, will allow the laboratory to reduce measurement uncertainties and eliminate the need for costly liquid helium. INTA, which has been a pioneer in the dissemination of primary Josephson voltage standard measurements throughout Europe, is the first calibration laboratory accredited in Spain.
The installation of the new quantum voltage standard at INTA represents a significant step forward in the adoption of quantum-based measurement technologies in Europe, and highlights the growing importance of quantum standards in advancing precision measurement capabilities.
