   Quantum-dot Cellular Automata (QCA) technology is a solution for implementation of the nanometer sized circuits and it can be a suitable replacement for CMOS. Similar to CMOS technology, designing the basic computational element such as adder with the QCA technology is regarded as one of the most important issues that extensive researches have been done about it. In this paper, a new efficient QCA full adder based on proposed MV32 gate is introduced which its novel structure leads to proper design technique selection and also its arrangement makes it very suitable. The proposed QCA full adder has 31 cells and its outputs are generated after the 0.75 of a clock time period. The proposed full adder is simulated using the QCADesigner2.0.3 simulation tool and has been compared with former works. The simulation results show that the proposed QCA full adder in terms of the number of used cells and occupied area is so better than others.
