A conductorless swap gate for ion-implanted contiguous-disk bubble devices using a folded minor loop and means for reversing the rotation of the rotating magnetic field is disclosed. The bubble device has a major loop, a folded minor loop, a swap gate containing at least one element positioned between the major loop and the folded end of the minor loop. The swap gate has a first portion for interchanging bubbles with the major loop, a second portion for transferring bubbles from a first region of the folded end of the minor loop, and a third portion for receiving bubbles from the second region of the folded end of the minor loop. Activation of the means for reversing the rotation of the rotating magnetic field causes the swap function to be effected. In a preferred embodiment, the device has a swap gate that has two elements and functions as a true swap gate.
