This paper presents the design, layout, and successful simulation of a QCA multiplexor. Quantum-Dot Cellular Automata (QCA) is one of several proposed computational nanotechnology paradigms that are being investigated as alternatives to CMOS at the nano-scale. QCA has been reported to offer relatively low power consumption and very high device density. Unlike conventional computers in which information is transferred from one place to another by means of electrical current, QCA transfers information by propagating a polarization state. In recent years, several researchers have started investigating relatively complex circuit architectures using QCA.
