Computer Applications of Josephson Junctions
The first superconducting device for digital applications was the cryotron . It did not succeed for a number of reasons including: (a) the mode of switching was based on the slow and power-consuming transition from the superconducting to normal state in metals; (b) the too early attempt to use a highly integrated technology; and (c) the lack of a theory of superconductivity. As an outgrowth of the BCS theory, the Josephson junction was discovered in 1962 (see historical discussion in Chapter I of this Proceedings). Its potential as a switching device which was superior to cryotrons was realized by J. Matisoo .
