Abstract

Fluxonic devices comprising a closed loop transmission line (30), an additional transmission line (32), and a junction (34) at which the closed loop transmission line and the additional transmission line meet are disclosed, which are embodiments of an apparatus comprising a fluxon container for containing one or more fluxons (12), 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 (10) having a length, a depth and a width and comprising a perturbation (3) in the length-wise direction, a mechanism for applying a driving electric current (14) in a depth-wise direction, and a magnetic field generator for generating a magnetic field (B) in a width-wise direction are also disclosed.
