Ultra-Thin Wires for Quantum Computing

Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, torture it over a flame until it nearly reaches its melting point and then pull it apart. The middle will thin out like taffy until it is less than half a micron across, and that, according to researchers at the University of Maryland, is how you fabricate ultrahigh transmission optical nanofibers, a potential component for future quantum information devices.
