In the last few decades, complementary metal-oxide-semiconductor (CMOS) based circuit design has reliably offered a required dimension reduction and for implementing high-speed low power integrated systems. But such a scaling process leads to many problems like second-order effects. As an alternative to CMOS design, researchers have identified a promising technology called Quantum Cellular Automata (QCA). It is encoding binary information In Quantum-dot Cellular Automata (QCA), the charge configuration of quantum dots is utilized to represent binary one or binary zero through an electron pair. Typically, QCA circuits have utilized majority and inverter gates for their logical functions. However, this study introduces a new design for the XOR logic gate which is based on a cell-level methodology, where the expected output is achieved through the influence of cells on each other. Unlike previous XOR/XNOR designs, our proposed gate does not rely on majority and inverter-based approaches. We have designed a new type of XOR gates based on cell interaction. Based on a similar design of XOR gate a 2:1 mux is designed. Using the novel 2:1 mux as the basic building block a 4:1 mux is constructed. This design of 4:1 mux can be used in a Multi Input Multi Output (MIMO) system like a router which helps to route packets between 'n' sources and 'n' destinations. [ABSTRACT FROM AUTHOR]
