Quantum-dot Cellular Automata

(electronics, computing)(QCA) Quantum logic circuits createdby orientating pairs of quantum cells so that their relativepositions determine their affect on each other. This isfunctionally analogous but structurally different from howindividual gates in integrated circuits are combined tocreate logical and memory circuitry.

The advantages of quantum-dot cellular automata overconventional circuitry are extremely small size/high density,low power requirements, and potentially high processingspeeds. Disadvantages (in 2000) are difficulty of fabricationand low yield.
