Quantum‐dot cellular automata (QCA) is an alternative complementary metal‐oxide‐semiconductor (CMOS) technology that is used to implement high‐speed logical circuits at the atomic or molecular scale. In this study, an optimal 2‐to‐4 decoder in QCA is presented. The proposed QCA decoder is designed using a new formulation based on the MV32 gate. Notably, the MV32 gate has three inputs and two outputs, which is equivalent two 3‐input majority gates, and operates based on cellular interactions. A multilayer design is suggested for the proposed decoder. Subsequently, a new and efficient 3‐to‐8 QCA decoder architecture is presented using the proposed 2‐to‐4 QCA decoder. The simulation results of the QCADesigner 2.0.3 software show that the proposed decoders perform well. Comparisons show that the proposed 2‐to‐4 QCA decoder is superior to the previously proposed ones in terms of cell count, occupied area, and delay.

基于MV32门的量子点细胞自动机技术中的Ultradense 2-4解码器

量子点自动机（QCA）是一种替代性互补金属氧化物半导体（CMOS）技术，用于在原子或分子规模上实现高速逻辑电路。在本研究中，提出了QCA中的最佳2-4解码器。建议的QCA解码器是使用基于MV32门的新公式设计的。值得注意的是，MV32门具有3个输入和2个输出，相当于两个3输入多数门，并基于细胞相互作用进行操作。建议针对所提出的解码器进行多层设计。随后，使用提出的2至4 QCA解码器，提出了一种新的高效3至8 QCA解码器架构。QCADesigner 2.0.3软件的仿真结果表明，所提出的解码器性能良好。
