- optical computing — (hardware) (Or "Optical Signal Processing") Operating on data represented using electromagnetic radiation, e.g. visible light, instead of the electrical signals used in a conventional electronic digital computer. Electronic digital computers are built from transistors. These form components that store data and logic gates that perform the low-level Boolean operations such as AND, OR and NOT that are the basis of all digital computation. The optical equivalent requires material with a non-linear refractive index such that light beams can interact with each other to perform the same Boolean operations. Though the photons that carry optical signals offer some theoretical advantages over the electrons that carry electronic signals, there are many practical problems that would have to be overcome before optical computing could compete in terms of cost, power and speed.

- quantum cell wire — (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.
