A pulse-driven Josephson arbitrary waveform synthesis system as a quantum AC voltage standard in KRISS

We report our progress in the Josephson arbitrary waveform synthesis system in KRISS. The system is based on the pulse-driven Josephson junction array, and currently we routinely produce arbitrary waveforms up to 100 mVrms amplitude with distortions smaller than 100 dBc. Precision waveform synthesis results are presented. Our future works will include AC-DC thermal transfer measurement and quantum noise source for Johnson noise thermometry.
