Balanced superconductive transmission line using Josephson tunnelling devices
Superconductive circuitry is described which consists of a transmission line having a terminal at each end thereof across which the output is measured, and which includes a plurality of pairs of Josephson tunnelling devices. Each Josephson tunnelling device of a pair is located in the transmission line equally distant from opposite end terminals thereof so that the transmission line is balanced. Each of the Josephson tunnelling devices has a zero voltage and a finite voltage state. Control means are provided for simultaneously controlling the voltage switching point of each Josephson device of each pair of said Josephson devices. The transmission line is pulsed with a current so that each Josephson tunnelling device of each pair of devices which are biased by the control means will switch into the finite voltage state causing reflections in the transmission line in a balanced manner so that the transmission line stabilizing time is minimized.
