Abstract

A fluxonic device including a closed loop transmission line; an additional transmission line and a junction at which the closed loop transmission line and the additional transmission line meet. An apparatus including a fluxon container for containing one or more fluxons; a fluxon interface along which a fluxon can propagate; a junction where the fluxon container and fluxon interface meet; and a controller for controlling a fluxon at the junction. An electromagnetic radiation generator comprising: a fluxon transmission line having a length, a depth and a width and including a perturbation in the length-wise direction; a mechanism for applying a driving electric current in a depth-wise direction; and a magnetic field generator for generating a magnetic field in a width-wise direction.
