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.
