As transistors decrease in size more and more of them can be accommodated in a single die, thus increasing chip computational capabilities. However, transistors cannot get much smaller than their current size. The Quantum-dot Cellular Automata (QCA) approach represents one of the possible solutions in overcoming this physical limit. Quantum-dot Cellular Automata (QCA) is a novel nanotechnology that promises smaller size, lower power consumption, with faster speed and is considered as a solution…
