In the past few years, CMOS semiconductor has been a growing and evolving technology in VLSI. However, due to the scaling issue and some other constraints like heat generation, high power consumption QCA (quantum cellular automata) emerged as an alternate and enhanced solution that provides a new technique of computing than CMOS in recent years. QCA is highly effective in implementing both Irreversible and Reversible logic, which has been shown to be incredibly efficient in terms of power consumption. A novel technique to data encryption called as SCV (select, cross, and variation) is demonstrated in this paper, which is based on ASCII to binary conversion and uses reversible logic. The data security procedure is aided by implementing SCV logic in reversible logic. Using Fredkin gate, it is built in QCA. QCADesigner tool has been used here for design and verification purposes. Total 80 cell counts and 0.14 μm 2 area are required. The theoretical data and the simulation results are the same as the intended circuit. Comparison to previous QCA architectural features is featured.

A New Nano-Scale and Energy-Optimized Reversible Digital Circuit Based on Quantum Technology

A nano-scale quantum-dot cellular automaton (QCA) is one of the most promising replacements for CMOS technology. Despite the potential advantages of this technology, QCA circuits are frequently plagued by numerous forms of manufacturing faults (such as a missing cell, extra cell, displacement cell, and rotated cell), making them prone to failure. As a result, in QCA technology, the design of reversible circuits has received much attention. Reversible circuits are resistant to many kinds of faults due to their inherent properties and have the possibility of data reversibility, which is important. Therefore, this research proposes a new reversible gate, followed by a new 3 × 3 reversible gate. The proposed structure does not need rotated cells and only uses one layer, increasing the design’s manufacturability. QCADesigner-E and the Euler method on coherence vector (w/energy) are employed to simulate the proposed structure. The 3 × 3 reversible circuit consists of 21 cells that take up just 0.046 µm2. Compared to the existing QCA-based single-layer reversible circuit, the proposed reversible circuit minimizes cell count, area, and delay. Furthermore, the energy consumption is studied, confirming the optimal energy consumption pattern in the proposed circuit. The proposed reversible 3 × 3 circuit dissipates average energy of 1.36 (eV) and overall energy of 1.49 (eV). Finally, the quantum cost for implementing the reversible circuits indicates a lower value than that of all the other examined circuits.

This paper presents a reversible nano‐scale decoder circuit. The decoder is designed by utilizing the new quantum‐dot cellular automata (QCA) format of the QCA1 gate. This QCA1 gate provides 34.25% less cell count with 54.37% less area than the best existing designs. Thus, the proposed QCA1 gate provides less area considering the best existing state‐of‐the‐art plans. The IBMQ‐based quantum realization of the QCA1 gate is also illustrated. The reversible full adder and subtractor circuits by employing the proposed decoder are likewise explored in this paper. A four‐input reversible OR‐gate is structured and concatenates with a decoder circuit to frame the circuit for full adder and subtractor. The energy dissipation by these QCA circuits is assessed to build up that QCA is an attractive option to CMOS for realizing reversible logic designs. The implemented results are compared with the truth table to ensure operational accuracy. The planned circuits can be utilized to structure reversible designs for nano‐communication.
