Abstract-Novel digital technologies always lead to high density and very low power consumption. One of these concepts is Quantum-dot Cellular Automata (QCA), which is one of the new emerging nanotechnology-based on Coulomb repulsion. This article presents three architectures of logical "XOR" gate, a novel structure of two inputs "XOR" gate, which is used as a module to implement four inputs "XOR" gate and eight inputs "XOR" gate using QCA technique. The two inputs, four inputs, and eight inputs QCA "XOR" gate architectures are built using 10, 35, and 90 Cells on 0.008 µm 2 , 0.036 µm 2 and 0.114 µm 2 of areas, respectively. The proposed "XOR" gate structure provides an improvement in terms of circuit complexity, area, latency and type of cross wiring compared to other previous architectures. These proposed architectures of "XOR" gate are evaluated and simulated using the QCADesigner tool version 2.0.3.

Novel digital technologies always lead to high density and very low power consumption. One of these concepts-quantum-dot cellular automata (QCA), which is one of the new emerging nanotechnologies, is based on Coulomb repulsion. This chapter presents a novel design of 2-input Exclusive-NOR (XNOR)/Exclusive-OR (XOR) gates with 3-input Exclusive-NOR (XNOR) gates which are composed of 10 cells on 0.006 μm 2 of area. A novel architecture of 3-input Exclusive-OR (XOR) gate is defined by 12 cells on 0.008 μm 2 of area. The proposed design of 2-input XOR/XNOR gate structures provide less area and low complexity than the best reported design. The simulation results of proposed designs have been achieved using QCA Designer tool version 2.0.3.

“…QCA uses the arrangement of intracellular electrons for binary representation instead of voltage level, so there is flow of current in this technique [3][4][5]. Many efforts have been made to implement the crucial components in logic circuits such as XOR [6][7][8][9][10][11] and multiplexer [12][13][14][15][16][17][18] using this nanotechnology. The multiplexer (MUX) was extensively utilized to implement many digital circuits such as RAM cells and ALU.…”

Quantum-dot Cellular Automata (QCA) is one of the most important computing technologies for the future and will be the alternative candidate for current CMOS technology. QCA is attracting a lot of researchers due to many features such as high speed, small size, and low power consumption. QCA has two main building blocks (majority gate and inverter) used for design any Boolean function. QCA also has an inherent capability that used to design many important gates such as XOR and Multiplexer in optimal form without following any Boolean function. This paper presents a novel design 2:1 QCA-Multiplexer in two forms. The proposed design is very simple, highly efficient and can be used to produce many logical functions. The proposed design output comes from the inherent capabilities of quantum technology. New 4:1 QCA-Multiplexer has been built using the proposed structure. The output waveforms showed the wonderful performance of the proposed design in terms of the number of cells, area, and latency.
