“…Recently introduced previous works in [ 20 , 21 ] used a three-input Exclusive-OR (TIEO) gate [ 12 ] to efficiently implement N-RAD designs. However, the robustness of this TIEO gate is not high enough.…”

“…Additionally, in the N-RAD construction period, the pipelining technique in the proposed CAS cell assists it to achieve fewer delays than the best existing ones. A comparison of QCA specifications among designs for the divider is given in Table 4 , and the proposed 3 × 3-bit QCA divider performs better than all of the prior best designs [ 20 , 21 ] in terms of latency.…”

“…In the literature, there have been several prior works on the implementation of QCA-based N-RADs with different techniques [ 17 , 18 , 19 , 20 , 21 ]. For example, the N-RAD divider in [ 17 ] was implemented with a single layer using a clock phase-based wire crossing.…”

“…N-RADs in [ 18 , 19 ] were designed as a multilayer structure based on majority gates and inverters. Recently, a new technical design work has been presented using a cell interaction-based XOR gate in [ 20 , 21 ]. However, these studies also have some limitations in implementation, because propagation delay throughout the wire was not well-considered.…”

“…Combination circuits such as multiplexers and full adders and sequential circuits such as flip-flops, counters, and memories can all be easily implemented visually in accordance with quantum logic [ 6 , 7 , 8 , 9 , 10 ]. Above all, if the structure of an operator such as adder, subtractor, multiplier, divider, and inverter increases, delay time, space complexity, and energy dissipation must be seriously considered in circuit configuration [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

Many studies have addressed the physical limitations of complementary metal-oxide semi-conductor (CMOS) technology and the need for next-generation technologies, and quantum-dot cellular automata (QCA) are emerging as a replacement for nanotechnology. Meanwhile, the divider is the most-used circuit in arithmetic operations with squares and multipliers, and the development of effective dividers is crucial for improving the efficiency of inversion and exponentiation, which is known as the most complex operation. In most public-key cryptography systems, the corresponding operations are used by applying algebraic structures such as fields or groups. In this paper, an improved design of a non-restoring array divider (N-RAD) is proposed based on the promising technology of QCA. Our QCA design is focused on the optimization of dividers using controlled add/subtract (CAS) cells composed of an XOR and full adder. We propose a new CAS cell using a full adder that is designed to be very stable and compact so that power dissipation is minimized. The proposed design is considerably improved in many ways compared with the best existing N-RADs and is verified through simulations using QCADesigner and QCAPro. The proposed full adder reduces the energy loss rate by at least 25% compared to the existing structures, and the divider has about 23%~4.5% lower latency compared to the latest coplanar and multilayer structures.

Aims: The Quantum-dot Cellular Automata explores a unique perspective in the arena of the architectural design of futurequantum computers, precisely due to its ultra-low packing density, high operating speed, and low power dissipation. On the other side, reversible computing allows the implementation of extreme low power-consuming circuits by avoiding energy dissipation during the time of computation. Objective: In this paper, we have explored the QCA design of reversible binary to gray and gray to binary code converters based on the application of a unique model of Feynman gate using the layered T exclusive-OR module (abbreviated in this work as LTEx Feynman gate). Methods: We have proposed algorithms to produce multi-control reversible binary to gray and gray to binary code converters and to develop cost-efficient QCA layouts. Results: Our systematic literature survey on the existing QCA designs of reversible binary to gray and gray to binary code converters helped us to compare and analyze the proposed design with the existing ones and identify it as the best design in terms of reversible, and QCA design metrics. Conclusion: Significant improvements in design metrics owing to successful experimentations over the previous designs are reported while instantiating 3X3,4X4, and 8X8 counterpart layouts.
