“…Multiplexers have been the focus of research due to their usage in arithmetic logic units and communication systems. Several QCA designs of fault-tolerant 2:1 MUX are reported in existing designs [29,33,[37][38][39][40][41][42][43][44][45], as shown in figure 9. The designs have been tested against single-cell misalignment, missing, displacement and addition faults.…”

“…Another design that has an extremely low cell count of only 15 cells also shows poor fault tolerance of 12.25% for cell omission defects. The design presented in figure 9(i) shows 2%, 100%, 97% and 100% fault tolerance to the four induced defects, respectively [37]. The other design that shows good fault tolerance with a small compromise on the cell count and cell area parameters is shown in figure 9(k) [33].…”

Quantum-dot cellular automata is a new and adroit technology currently under extensive research for the post-CMOS era VLSI chip design. Quantum-dot cellular automata (QCA) has promised more reliable, fault-tolerant, and secure chip designs. Also, while analyzing the QCA circuits for power and energy dissipation, promising results have been reported that suggest that the QCA circuits dissipate significantly less energy and operate very close to the Shannon-von Neumann-Landauer (SNL) limit. Security is another concern that has led to the development of QCA based security systems like physically unclonable functions and true random number generators. In this paper, a survey of different fault-tolerant and QCA based security circuits has been provided, along with the discussion of critical design aspects and parameters in QCA technology.

“…QCA based security need and a new hardware security solution for identification of circuits with a comparison with other circuits have been presented in [25]. New design of Multiplexer with full fault tolerance and use of cell redundancy is presented in [26]. Realization of Least Significant Bit (LSB) based encoder/decoder steganography circuit has been designed by proposing a new XOR Gate where the image is divided into 3 channels and XOR operation within the key and message is done and embedded bits in the LSB of the image [27].…”

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.
