Abstract

We performed a preliminary calibrated measurement of the output power of a Josephson arbitrary waveform synthesizer up to 1 GHz.We present the results and measurement procedure for generating quantum-based signals using an array of Josephson junctions operating at cryogenic temperature and calibrating those signals to transfer the on-wafer quantum-based accuracy to room temperature.
