quantum cell wire
     
         (Or "quantum wire", "binary wire")
        {Quantum cells} arranged in a line to carry signals.  Adjacent
        cells with the same orientation are at a low energy state and
        a change of orientation at one end of a quantum wire
        propagates along the wire, transmitting a signal.  However,
        unlike conventional wire, since only the orientation of charge
        pairs changes, no current flows.
     
        Circuits created using quantum cell wires are referred to as
        Quantum-dot Wireless Digital Circuits, see {quantum dot},
        {Quantum-dot Cellular Automata}.
