josephson effect - Science Definition
An effect in which electron pairs undergo quantum tunneling with zero resistance across a barrier separating two superconductors. The effect can be manipulated by varying a magnetic field at the junction where the tunneling occurs and is being investigated as a possible part of the design of high-speed switches for computer microprocessors. The Josephson effect is named after its discoverer, Welsh physicist Brian David Josephson (b. 1940).
