“…Figure 1b shows the orientation of a QCA cell and its possible two polarizations. Considering the position of pair of charged electron inside the cell, polarizations are differentiated with the following two conditions: (À 1) for binary logic '0' and (þ1) for binary logic for that of '1' [26,27]. A QCA cell can just reside in either of the two potential states of the cell polarization.…”

Quantum‐dot cellular automata (QCA) is gaining worldwide popularity due to its higher device concentration, lower power indulgence, and better switching speed. The information flows in QCA with the polarization state defined by the placement of electrons instead of current flow. The cell interaction principle under the influence of the clocking zone controls the cell placement during QCA circuit design. Most of the designs reported so far used random cell placement, which has no fabricating sense. Moreover, it is equally important for a cell placement algorithm to follow a realistic, regular underlying clocking scheme to maintain proper routing channels. In this regard, a systematic cell placement for the combinational logic circuit in QCA is proposed using the widely accepted underlying regular clocking scheme, universal, scalable and efficient (USE). The proposed method traverses all possible paths of a combinational logic circuit from output to input to build the desired circuit generating the automatic cell layout. A grid of clock zone of USE clock scheme is considered in the initial layout driving different paths of the circuit and finally evolves as the desired circuit. The generated automatic QCA layouts are competitive in occupied area, delay, and its cell count, which advocates the significance of such a scheme.

“…The demultiplexer is a beneficial electronic circuit, which can be utilised in signal routing and data communications [21]. This circuit attains an input signal and leads it to the required output line with the utilisation of the choosing line information [22,23]. It converts a serial data signal into parallel data signals [24].…”

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.
