Abstract

The new quantum SI opens the route to link the base unit definitions to fundamental constants of nature. In the spirit of the quantum SI, a similar traceability route can be implemented for alternating electrical quantities, such as electrical power. Its implementation is summarized in the present paper along with the main steps about the realization of a quantum-based sampling power standard carried out in the framework of the EMPIR project Quantum Power. A programmable Josephson voltage standard (PJVS) based on a 1-V SNS binary array provides the traceability of the power standard. The PJVS has been integrated into an existing sampling power standard and its main purpose is the real-time calibration of high-precision waveform digitizers using a new synchronous quantum power multiplexer (SQPM). Measurement scenarios and experimental characterization aimed at evaluating the gain and phase errors of the system constituents, and in particular of SQPM, are presented.
