< electronics , computing > (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 .
