“…Reviews of the developments up to this time are given for example by Niemeyer (1989), Kautz (1992) and Pöpel (1992). These SIS arrays with multiple Shapiro steps led to the adoption of JVSs for the representation of the volt on 1 January 1990 (Quinn 1989).…”

The discovery of the Josephson effects 50 years ago initiated a revolution for electrical voltage metrology. This revolution started with single Josephson junctions delivering a few millivolt at most. Meanwhile, highly integrated series arrays containing more than 10 000 or even 300 000 junctions have been developed and fabricated for output voltages up to 10 V. Josephson voltage standards are nowadays used in many laboratories worldwide for dc applications. After their adoption for the representation of the unit of voltage in 1990, the focus of research shifted towards programmable Josephson series arrays. The increasing interest in highly precise ac voltages resulted in new developments for their metrological applications in the last 15 years. This paper summarizes the principal contributions from PTB to the present state of Josephson voltage standards with particular focus on developments and applications for ac standards in metrology and our proof-of-concept demonstrations. The presentation includes the two most promising versions of ac standards, being the programmable Josephson voltage standard based on binary divided series arrays and the Josephson arbitrary waveform synthesizer based on a pulse-driven series array.

This paper reviews the present state of modern Josephson voltage standards. The presentation focuses on conventional dc standards based on underdamped superconductor-insulator-superconductor junctions and programmable standards based on overdamped superconductor-insulator-normal conductor-insulator-superconductor junctions. The current developments of ac standards on the basis of pulse-driven arrays and single flux quantum-based voltage multipliers are briefly summarized.

Famous applications of Josephson junctions have successfully been established in electrical metrology for high‐precision measurements. The main important representative of a metrological application is the Josephson voltage standard initially used for dc measurements. Meanwhile, the developments are focused on Josephson voltage standards for ac applications. These quantum voltage standards for output voltages up to 10 V contain series arrays of 100 000 Josephson junctions or even more. This chapter describes the development and present status of modern Josephson voltage standards.
