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.

Understanding the mechanisms associated with fertility and disease management in animals remains challenging. Continuing advances in nanotechnology provide new tools and alternative approaches for the investigation of these mechanisms. Fluorescent quantum dot nanoparticles, for example, have unique physicochemical properties, which allow for in vivo and in vitro imaging in various areas of life sciences. Traditional quantum dots contain heavy metal semiconductor cores, which have raised concern over their potential for toxicity. The majority of available quantum dots today prevent heavy metal release with additional chemical and polymer layers for safe water solubility. In this chapter, the most widely used quantum dots made of cadmium selenide, which possess great potential for real-time imaging in disease detection and reproductive medicine, are discussed.

Quantum-dot cellular automata (QCA) is considered as a top candidate for nanoscale technologies with unique features such as very low occupancy and ultralow power consumption. Despite the potential benefits of QCA technology over CMOS technology, QCA circuits are highly prone to defects. Therefore, a demand has risen in designing fault-tolerant circuits. In this research, a novel fault-tolerant five-input majority gate is first suggested, and then it is evaluated by implementing a variety of faults such as cell omission, cell displacement, and extra-cell deposition. The evaluation results reveal that the proposed structure is 100%, 51.85%, and 18.8% fault-tolerant under extra-cell deposition, single-cell omission, and double-cell omission, respectively. Moreover, two single-layer and coplanar fault-tolerant QCA full-adders are offered using the suggested fault-tolerant structure. The stability of the presented single-layer full-adder has also been investigated under single and double cell omission defects. The evaluation outcomes show that the suggested fault-tolerant single-layer full-adder has a high stability in Sum and C out outputs compared with other full-adders. In order to validate the functionality of the suggested fault-tolerant five-input majority gate, a number of physical investigations are given. The QCADesigner 2.0.3 software has been used to evaluate the simulation results.KEYWORDS five-input majority gate, circuit design, fault-tolerant, full-adders, nanotechnology, quantum-dot cellular automata (QCA)
