Quantum‐dot cellular automata (QCA) is an emerging technology to design logic circuits at the nanoscale level. It has the potential to replace the complementary metal oxide semiconductor (CMOS) technology. In this paper, an optimal, single layered, single clocked 1:2 demultiplexer (DeMux) circuit is proposed using 19 QCA cells in QCA technology. Proposed 1:2 DeMux circuit is further utilized for designing of 1:4 DeMux and 1:8 DeMux circuits using 72 and 206 QCA cells respectively. DeMux is an important module at the receiver side in the communication system. The performance of the proposed DeMux circuits are checked and compared with the available similar designs using QCA Designer‐E. Proposed 1:2 DeMux decreases 79.17% layout cost and 50% clock latency as compared to the best reported work in the literature. Proposed 1:4 DeMux reduces 48.57% cells count and 40.63% total area while proposed 1:8 DeMux cuts 63.54% cells count and 64.54% total area as compared to best reported similar works in the literature. Energy dissipation pays an important role to design the energy efficient circuits at nanoscale level. Energy dissipations are estimated using QCA Designer‐E and QCA Pro tools. Proposed 1:2 DeMux saves 8.20% total energy dissipation as compared to the existing design.

Quantum‐dot cellular automata (QCA) are prospective nanotechnology with striking performance to tackle the shortcomings of complementary metal‐oxide‐semiconductor (CMOS) transistor‐based technology such as fabrication dimensions and switching speed. The demultiplexer, as a crucial component for the design of many logic circuits, comprises a circuit for separating the multiplex data into the component data. The demultiplexer is highly utilised in the communication system for building serial data lines to parallel ones. So, its efficient schematisation has turned to an issue that has captured the concentration of the investigation group. Therefore, a novel structure of QCA‐based one to two demultiplexers is proposed, and it is employed to design one to four demultiplexers. QCAdesigner software, as a powerful layout and tool for simulation, is utilised for evaluating the validity and practicality of the proposed structures. The detailed evaluation of proposed layouts shows excellent performance than prior operations, and notable developments regarding the occupied area, cell count, and latency.
