Element Technology of Quantum-Dot Cellular Automata Based Circuit Design

Abstract

In this paper, we briefly introduce the element technology for constructing combinational circuits on Quantum-dot Cellular Automata (QCA). There are various combinational circuits including encoder, decoder, adder, subtractor and multiplexer. For the design of the circuits in QCA, there are essential element technology such as wire crossing, inverting structure and majority gate. Thus we simply present the important factor technology to design efficient QCA structures.
