The control of electrons at the level of the elementary charge e was demonstrated
experimentally already in the 1980s. Ever since, the production of an electrical current ef, or …

Superconductor electronics combines passive and active superconducting components and
sometimes normal resistors into functional circuits and systems that also include room …

Bloch oscillations in small Josephson junctions were predicted theoretically as the quantum
dual to Josephson oscillations. A significant consequence of this prediction is the …

Scaling of quantum computers to fault-tolerant levels relies critically on the integration of
energy-efficient, stable, and reproducible qubit control and readout electronics. In …

This paper reviews the development and use of Josephson voltage standards over the last
30 years, including classical dc standards, programmable standards based on binary …

For decades, the quantum behavior of Josephson junctions has been employed as intrinsic
standards for voltage metrology. Conventional dc Josephson voltage standards have been …

The book develops a comprehensive understanding of the surface impedance of the oxide
high-temperature superconductors in comparison with the conventional superconductor …

For four decades semiconductor electronics has followed Moore's law: with each generation
of integration the circuit features became smaller, more complex and faster. This …

Recent measurements using acoustic gas thermometry have determined the value of the
Boltzmann constant, k, with a relative uncertainty less than 1× 10− 6. These results have …

The establishment at PTB of an AC Josephson voltage standard (Josephson Arbitrary
Waveform Synthesizer-JAWS) based on pulse-driven Josephson arrays is focused on …
