Josephson junction

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia, Hutchinson 0.01 sec.
Josephson junction
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 computer circuits, they have been used thus far in medical instruments that sense brain waves.
Josephson junction [′jō·səf·sən ‚jəŋk·shən]
(cryogenics)
A thin insulator separating two superconducting materials; it displays the Josephson effect.
(electronics)Josephson Junction - A type of electronic circuit capable of switching at very high speeds when operated at temperatures approaching absolute zero. The low power dissipation of a Josepshson Junction makes it useful in high density computer circuits.
