Josephson junction

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia, Hutchinson 0.02 sec.

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.

(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.
