Quantum-dot Cellular Automata (QCA) technology has become a promising and accessible candidate that can be used for digital circuits implementation at Nanoscale, but the circuit design in the QCA technology has been limited due to fabrication high-defect rate. So, this issue is an interesting research topic in the QCA circuits design. In this study, a novel 3-input Fault Tolerance (FT) Majority Gate (MG) is developed. Accordingly, an efficient 1-bit QCA full adder is developed using the developed 3-input MG. Then, a new 4-bit FT QCA Ripple Carry Adder (RCA) is developed based on the proposed 1-bit FT QCA FA. The developed circuits are implemented in the QCADesigner tool version 2.0.3. The results indicate that the developed QCA circuits provide advantages compared to other QCA circuits in terms of double and single cell missing defect, area and delay time.

All nano-technologies including “QCA” (Quantumdot Cellular Automata) is widely used in today‟s world to reduce the power dissipation, area and delay. “QCA” is a magnify technology with huge advantages such as: high-speed, highdensity, faster-switching and higher clock-frequency which is rapidly used for Integrated-Circuit (“IC”) design. Quantum-dot Cellular Automata is an useful and appropriate alternative of the “CMOS-technology” because of its various advantages such as: it‟s high-frequency, less power leakage and less required area. An “ALU” (arithmetic and logic unit) is applying for all types of arithmetic-logical performances and it widely used in digital circuits for all types of arithmetic and logical operations. The reversible-Logic an authentic solution in low-power and low-cost technology. This paper presents a latest 3-D or multilayer structure of ALU using reversible-computing and also non-reversible logic which gives a comparative outcome with low supply-power and delay. The complexity of the formation and the engrossed size of this model is low. „AND-Gate‟, „OR-Gate‟ ,„XOR-Gate‟ and the reversible „TSG-Gate‟ and also the non-reversible model of “FullAdder” are used to design the suggested model of this paper through the “QCA Designer” software (for simulation).This design reduce the size of the model up to 0.11 µm2 with three layers which is also compared to the formation in the “Xilinx” software.

“…QCA is a field-coupled nano technology where information travels with the help of local interaction between the electrons. Thus, QCA is considered as one of the most propitious nanoelectronic technologies [2,4]. Now-a-days, the most important requirement of any computational system is processing speed and low power consumption.…”
