Experimental Device for Nanowires (IMAGE) Delft University of Technology Caption Electronmicroscopy image of two nanowires (dark blue) in a ring of superconducting material. With the two contacts on the top nanowire a quantum dot is formed. The high level of control enables the observation of a new and divergent type of superconductivity. The ring measures 10 by 3 micrometers.
