In the present digital Nano-electronic era, the Quantum cell-based QCA (“Quantum-dot cellular automata”) technical platform is a suitable alternative to the transistor-level-based C.MOS-Technologies (Complementary metal oxide semiconductor technology).In this paper, the QCA technology is used to design multilayer, 3D, multi-bit (up to 8bit is selected) quantum low powered, high speed, optimum cost-effective Barrel Shifter. In the proposed Barrel-Shifter design, the reversibility is properly checked by using 2:1 MUX, and response analysis is also discussed appropriately. Along with this, the presented structures in this paper are compared with existing advanced related works and these comparisons are mainly based on an occupied unit area, area-based power consumption, latency, complexity, and cost. Additionally, the stability checking of the proposed multilayer Barrel-Shifter structure (in terms of output-polarization) is also included in this work based on the temperature tolerance and layer separation gap.

Reversible logic is used increasingly to design digital circuits with lower power consumption. The parity preserving (PP) property contributes to detect permanent and transient faults in reversible circuits by comparing the input and output parity. Multiplication is also considered one of the primary operations in both digital and analog circuits due to its wide applications in digital signal processing and computer arithmetic operations. Accordingly, Vedic mathematics, as a set of techniques sutras, has become popular and is extensively used to solve mathematical problems more efficiently and faster. This work proposes three PP reversible blocks, N1, N2, and N3, which are used to develop a novel effective 2‐bit PP reversible Vedic multiplier and 4‐bit ripples carry adders (RCAs). Moreover, 2‐bit Vedic multiplier and RCA are used to develop the 4‐bit PP reversible Vedic multiplier. The proposed designs outperform the most relevant state‐of‐the‐art structures in terms of garbage output (GO), constant input (CI), gate count (GC), and quantum cost (QC). Average savings of 22.37%, 35.44%, 35.44%, and 34.76%, and 17.76%, 26.60%, 24.52%, and 27.27% respectively, are observed for two‐bit and four‐bit PP reversible Vedic multipliers in terms of QC, GO, CI and GC as compared to previous works.

“…Recently, reversible-based designs have been growing interest as they have decreased heat dissipation [1]. Because energy loss is a critical concern with circuits that have been non-reversible [2]. In another word, the loss of each piece of information results in a kTLn2 Joule of heat energy in a non-reversible calculation, according to Landauer [3], where k is the Boltzmann constant and T is the absolute computing temperature.…”

“…Therefore, reversible circuit structures will replace traditional circuits in the near future. In addition, the number of inputs in reversible circuits is the same as the number of outputs [2]. In contrast, complementary metal-oxide semiconductors' power efficiency and feature size (CMOS) have reached their saturation points [4].…”

Reversible logic has attracted significant attention recently due to its inherent ability to decrease energy dissipation, which is the primary need of low-power digital circuits. One of the newest areas of study is reversible logic, which has applications in several areas, including nanotechnology, DNA computing, quantum computing, fault tolerance, and low-power CMOS. On the other hand, Quantum-dot Cellular Automata (QCA) is one of the stunning approaches that can be used as an alternative to traditional technologies. An Arithmetic and Logic Unit (ALU) is considered for performing essential instructions such as addition, subtraction, division, multiplication, and logic operations, including OR, XOR, AND, and XNOR. In other words, ALUs perform essential functions in digital processing circuits because of their wide applications in Central Processing Units (CPUs). Accordingly, ALUs have become a necessary part of microprocessors and are extensively used to solve procedural problems more efficiently and reliably. Hence, this paper proposes an efficient ALU with low power and high speed. At first, a full adder and a 4:1 multiplexer circuit are developed using a unique reversible gate. At last, using all the suggested circuits, an ALU with four mathematical and logical operations is developed. Moreover, several physical validations are presented to confirm the functionality of the QCA gate. The simulations of the structures and power consumption analysis are performed using QCADesigner 2.0.03 and QCAPro software. The suggested ALU's consumption power under various energy ranges (0.5 Ek, 1 Ek, and 1.5 Ek) showed significant advancements from previous designs.
