Nettet6. aug. 2024 · We report on the calibration of quantum-based radio frequency waveforms generated by a Josephson arbitrary waveform synthesizer system. We measure these waveforms using a vector network analyzer and calibrate them at 4 K using a custom-designed cryogenic on-wafer multi-line thru-reflect-line calibration kit and a two-tier … NettetVerschiedene Versionen breitbandiger On-Chip-Leistungsteiler basierend auf dem Konzept der Wilkinson-Teiler wurden entwickelt und untersucht, um das von der PTB entwickelte pulsgetriebene Josephson-Spannungsnormal (JAWS) zu optimieren und den experimentellen Aufbau zu vereinfachen. Ziel dieser Entwicklung ist es, die Bandbreite … NettetWe 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 … pho cookeville tn
