There have also been attempts to use the
Josephson Effect to create ordinary processors.
The realisation of the ampere is currently derived indirectly from resistance or voltage, which can be realised separately using the quantum Hall effect and the
Josephson Effect. A fundamental definition of the ampere would allow a direct realisation that National Measurement Institutes around the world could adopt.
His theory predicted the properties of a supercurrent through tunnel barriers known as the
Josephson effect.
The experimental development of the
Josephson effect allowed voltages to be linked to unchanging fundamental constants with extremely high precision and stability [8].
The team interprets the oscillation within the lattice that creates the pulses as the first evidence in a condensate of a phenomenon called the
Josephson effect. In the effect, previously seen in superconductors and superfluids and of wide use in electronics, an oscillating flow of particles passes through a barrier.

Josephson Effect, New York: Wiley-Interscience Publications, 1982, pp.
At about the same time supercurrent junctions were found to exhibit the
Josephson effect, namely, the flow of an electron-pair tunneling current through an insultor separating two superconductors.
Along with four other scientists, the Cardiff physicist won the Nobel Prize for physics in 1973 for his theory on predicting the properties of a supercurrent through tunnel barriers - known as the "
Josephson effect".
