  text: We demonstrate a method for manipulating small ensembles of vortices in multiply
    connected superconducting structures. A micron-size magnetic particle attached
    to the tip of a silicon cantilever is used to locally apply magnetic flux through
    the superconducting structure. By scanning the tip over the surface of the device
    and by utilizing the dynamical coupling between the vortices and the cantilever,
    a high-resolution spatial map of the different vortex configurations is obtained.
    Moving the tip to a particular location in the map stabilizes a distinct multivortex
    configuration. Thus, the scanning of the tip over a particular trajectory in space
    permits nontrivial operations to be performed, such as braiding of individual
    vortices within a larger vortex ensemble—a key capability required by many proposals
    for topological quantum computing.
