Abstract: A passive bubble replicator is achieved by adding to a stage of a multistage, fine-grained, field-access bubble propagate circuit, magnetic elements of a geometry to provide laterally spaced localized attracting poles and a repelling intermediate pole in the propagation path. Normal operation of the finegrained propagate circuit provides poles which first expand a bubble laterally and thereafter cooperate with the intermediate pole to cut the expanded bubble.
