(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
