Summary Quantum‐dot cellular automata (QCA) is one of the proposed nanotechnologies in the electronics industry, which offers a new construction for scheming digital circuits with less energy consumption on the nanoscale and possibly can be an appropriate replacement of complementary metal‐oxide semiconductor (CMOS) technology. Nanocommunication in QCA has attracted a wide range of researcher's attention. However, there is still a broad scope to design QCA‐based architecture for nanocommunication. The multiplexer is hugely used in the telecommunication system and transmits multiple data at the same time. Therefore, in this paper, a useful structure to implement a 2 to 1 multiplexer based on the novel XOR gate is presented and is used as a module to implement the 4 to 1 and 8 to 1 multiplexers. Simulations using QCADesigner tool are done to check the performance of the suggested designs. The 2 to 1, 4 to 1, and 8 to 1 QCA multiplexer structures utilize 22, 92, and 260 cells and consume 0.03, 0.12, and 0.40 μm 2 of area, respectively. They have shown that the suggested designs have stable and applicable structures regarding area, cost, and complexity.
