Josephson-junction meaning

jōzefsən, jōsəfsən
An insulating barrier separating two superconducting materials and producing the Josephson effect.
noun
A low-power, high-speed electronic switching device consisting of a thin insulator between two superconducting metals: it operates at a temperature near absolute zero.
noun
An ultra-fast switching technology that uses superconductor materials, originally conceived by Brian Josephson. Circuits are immersed in liquid helium to obtain near-absolute zero degrees required for operation. Switching takes place in a few picoseconds. Although Josephson junctions have not materialized for ordinary computer circuits, they have been used thus far in medical instruments and quantum computers. See quantum computing.
(physics) A weak insulating barrier between two superconductors, used as an ultrafast switch.
