josephson junction - Computer Definition
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.
