In the domain of digital computing, the quest for higher performance, energy efficiency, and miniaturization has driven the exploration of alternative technologies to overcome the limitations of traditional Complementary Metal-Oxide-Semiconductor(CMOS) technology. Quantum Dot Cellular Automata (QCA) has emerges as a promising candidate for revolutionizing the field of digital circuits, offering the potential to push the boundaries of speed and power efficiency. Arithmetic Logic Unit, also known as ALU, is responsible for carrying out logical and arithmetic operations based on the input operands. The proposed Arithmetic Logic Unit is fed input through layering, which results in reduced occupation area and cell count. It consists of half adder and NAND gate followed by two 2 x1 Multiplexer. The proposed design of a half adder and NAND gate (used for And operation) uses less space, less cells, and low energy dissipation than the existing design.
