QUANTUM METROLOGY PROJECT (Jun/2024 - Dec/2025)
This project aims to research the accuracy improvement technology using a
quantum voltage chip, to obtain a reference AC voltage to calibrate metering
devices. It also includes the research on error monitoring methods of digital
metering equipment driven by high accuracy measurement data.
R&D Nester will setup the Quantum Voltage Platform that includes a 10 V PJVS - Programmable Josephson Voltage Standard array chip, Cryoprobe, Dewar with Liquid Helium and Microwave source, for the reference voltage source.
The Digital Metering Platform provided by CEPRI will be installed at the R&D NESTER Lab, to evaluate the error of metering equipment (analogue and digital) on short and long term. A machine learning model will be developed to predict this error.
