Quantum-Dot Cellular Automata (QCA) is an emerging nanotechnology, with the potential for faster speed, smaller size, and lower power consumption than transistor-based technology. The basic logic circuits of the system are inverter and majority gates. Quantum-Dot Cellular Automata has a simple cell as the basic element. The cell is used as a building block to constructgates and wires. These structures were designed with minimum number of cells by using cell minimization technique. This project utilizes the QCA characteristics to design the Ripplecarry adder. A Ripple carry adder is a logic circuit in which the carry-out of each full adder is the carry-in of the succeeding next most significant full adder. Multiple full adder circuits can be cascaded in parallel to add an N-bit number. The layout of a ripple-carry adder is simple, which allows fast design time. The experimentation with the proposed designs have been successfully verified through the QCA Designer tool.

Keywords- Quantum dot cellular automata, Ripple carry adder, Majority gates, QCADesigner
