Datasets for the four published figures in the Paper "AC Metrology Applications of the Josephson Effect ". This paper is being submitted to Applied Physics Letters Special Topic, "Advances in Quantum Metrology,"https://publishing.aip.org/publications/journals/special-topics/apl/advances-in-quantum-metrology/ .Abstract of the paper:The performance of programmable voltage signals that exploit the quantum behavior of superconducting Josephson junctions continues to improve and enable new capabilities for applications in metrology, communications, and quantum control. We review advances in pulse-driven digital synthesis techniques with Josephson-junction-based devices. Unprecedented performance for synthesized voltage waveforms has been achieved at different frequencies, including rms amplitudes of 4 V at 1 kHz, 50 mV at 50 MHz, and 22 mV at 1.005 GHz. Josephson pulse generators have also successfully controlled and characterized superconducting qubits with a gate fidelity of 99.5%.
