Quantum Cellular Automata (QCA) is an alternative promising nanotechnology for semiconductor transistor based technology. QCA benefits from several features such as high speed, low power consumption and can be used for extremely dense structures. One of the important issues in arithmetic circuits is design of full adder/full subtractor (FA/FS respectively). Our main contribution in this paper is proposing a one-bit FA/FS which benefits from less cell counts compared to the state-of-the-art technologies. The proposed QCA FA/FS ameliorate the number of cells in comparison with the best FA/FS studied in the literature. As well as the mentioned feature, temperature analysis of suggested circuit shows that our design is more tough compared to the previous works.

“…Tese multilayer designs do not incorporate more than three layers. Two QCA FAs are presented in [69,70] which are implemented using one 5-input majority gate, one 3-input majority gate, and two inverter gates. Te QCA FA presented [71] is implemented with only one 3-input majority gate and one XOR gate.…”

Being one of the promising techniques for future computing systems, quantum-dot cellular automata (QCA)-based circuit design has gained massive interest among researchers due to which numerous QCA-based full adder (FA) circuits have been designed. Due to numerous QCA FA circuits available in the existing literature, researchers find it difficult to invest the time to search, implement, simulate, and analyze QCA FAs to find the best-suited design according to their needs. Existing review articles do not present a complete overview and performance comparison of QCA FAs. Also, the existing articles do not include quite a number of QCA FA designs in the literature review. As a result, a detailed review including all possible QCA FAs becomes essential. Therefore, rather than going for a new QCA FA design, this research aims to aid researchers by providing an extensive literature review and comprehensive study on existing QCA FAs. A total of 47 QCA FAs have been considered for analysis. The QCA FA implementation method and performance parameters are summarized in a tabular manner to provide a quick overview and comparison of the QCA FAs.

Recently, quantum dot-cellular automata (QCA) has fascinated much attention because of its potential less area consumption, low power usage, less intricacy, and low delay. The full-adder circuit is used in this technology for several procedures, like multiplication, subtraction, and division in the arithmetic logic unit. For this reason, the full-adder is generally investigated as a central unit in the development of QCA technology. The present investigation demonstrates a new efficient QCA-based full-adder layout utilizing the TIEO gate and new 3-input majority gate. In this design, the inputs get inside one side, and the outputs are derived from another circuit side. Other cells do not embrace the output and input signals, and they may simply be available, helping produce a more impressive circuit layout. Concretely speaking, in this design, the 0.02 μm 2 region and the latency of the 0.5 clock cycle have been implemented using only 18 cells. Utilizing the QCADesigner tool, the suggested design in the current investigation has been functionally approved. The simulation outcomes show that this layout conducts properly and works faster than the oldest designs.
