And voltage standards are based on Josephson junctions, which are one of the technologies that are being used and explored for QIS applications.
There are three kinds of superconducting qubits--flux, charge, and phase qubits; all use Josephson junctions. Superconducting loops that include a Josephson junction allow current to flow clockwise and counterclockwise simultaneously, a superposition of states.
In this case, we may regard the Josephson junction as a curvature-to-voltage converter with the following ratio (m is the free electron mass):

He has worked on a broad range of topics within the field of superconducting electronics, including Josephson junction array oscillators, single flux quantum logic, ac and dc Josephson voltage standards, Josephson waveform synthesis, and noise thermometry.
where [I.sub.c] is the critical current of a Josephson junction in the 2D array, [k.sub.B] is the Boltzmann constant, T is the absolute temperature, and [[DELTA].sub.c] is the collective Coulomb barrier of the array.
"The principal advantage of using the Josephson junction is that it can span the low and high frequency ranges covered by other, significantly more expensive devices," said Yuri Divin, of the Research Centre Juelich.
Josephson junction arrays represent the most stable and predictable standard voltage source.
When two or more domains are in close proximity, a superconductor-normal conductor-superconductor Josephson junction is formed.
In this paper we describe the main features of the Josephson effect and the different developed systems to elaborate Josephson junctions with H[T.sub.c].
