Quantum dot Cellular Automata (QCA) is a branch in nano-electronic for design the logical gates and circuits. The QCA logic gates composed from basic elements which are named as QCA cells. A QCA cell is a nanometer structure that constructed from nanometer semiconductors and capacitors. In QCA scope, the authors just have majority and inverter logic gates because of this fact that QCA cells perform their logical functions based on columbic forces between them and other QCA logic gates can be constructed by majority and inverter gates and QCA wires. Clock signals controls the QCA cells activities and states and the clocked QCA cells perform the delays and other features for design the conventional and sequential logic circuits.
