Ballistic Quantum Wires Conduct Superbly

haleos writes: "Physics Web ran an article on Ballistic Quantum Wires which allow resistance free current flow without the super-low temperatures of present-day superconductors. Just think of what a superconducting quantum wire could do for the speed of your future pocket computer!" Rather than low temperatures keeping atoms in line, these wires gain their properties from ultra-precise manufacturing techniques.
