“…To address these troubling issues, a shift from conventional VLSI computing to molecular, DNA, and quantum computing as some viable alternative options might be helpful. The Quantum-dot Cellular Automata (QCA) is one of these intriguing realization technologies that has garnered greater attention recently (9)(10)(11)(12)(13) because of several advantageous qualities. These challenges prompted the solution introduced by Lent in 1997 involving QCA [1].…”

Quantum dot cellular automata (QCA) is one of the newest nanotechnologies. The conventional complementary metal oxide semiconductor (CMOS) technology was superbly replaced by QCA technology. This method uses logic states to identify the positions of individual electrons rather than defining voltage levels. A wide range of optimization factors, including reduced power consumption, quick transitions, and an extraordinarily dense structure, are covered by QCA technology. On the other hand, the serial-parallel multiplier (SPM) circuit is an important circuit by itself, and it is also very important in the design of larger circuits. This paper defines an optimized circuit of SPM circuit using QCA. It can integrate serial and parallel processing benefits altogether to increase efficiency and decrease computation time. Thus, all these mentioned advantages make this multiplier framework a crucial element in numerous applications, including complex arithmetic computations and signal processing. This research presents a new QCA-based SPM circuit to optimize the multiplier circuit's performance and enhance the overall design. The proposed framework is an amalgamation of highly performance architecture with efficient path planning. Other than that, the proposed QCAbased SPM circuit is based on the majority gate and 1-bit serial adder (BSA). BCA circuit has 34 cells and a 0.04 μm 2 area and uses 0.5 clock cycles. The outcomes showed the suggested QCA-based SPM circuit occupies a mere 0.28 µm² area, requires 222 QCA cells, and demonstrates a latency of 1.25 clock cycles. This work contributes to the existing literature on QCA technology, also emphasizing its capabilities in advancing VLSI circuit layout via optimized performance.Ključne besede: množilnik, serijsko-vzporendo, binaren množilnik, nano, komunikacije na osnovi QCA Kvantno vezje zaporedno-paralelnega množilnika z uporabo učinkovitega zaporednega seštevalnika v nano merilu PovzetekKvantni točkovni celični avtomati (QCA) so ena od najnovejših nanotehnologij. Tradicionalno tehnologijo komplementarnih kovinsko oksidnih polprevodnikov (CMOS) je odlično nadomestila tehnologija QCA. Ta metoda uporablja logična stanja za določanje položajev posameznih elektronov in ne definira napetostnih nivojev. Tehnologija QCA pokriva številne optimizacijske dejavnike, vključno z manjšo porabo energije, hitrimi prehodi in izredno gosto strukturo. Po drugi strani pa je vezje serijsko-paralelnega množilnika (SPM) samo po sebi pomembno vezje, zelo pomembno pa je tudi pri načrtovanju večjih vezij. Članek opredeljuje optimizirano vezje SPM z uporabo QCA. V njem lahko združimo prednosti serijske in vzporedne obdelave ter tako povečamo učinkovitost in skrajšamo čas računanja. Zaradi vseh omenjenih prednosti je torej to seštevalno ogrodje ključni element v številnih aplikacijah, vključno s kompleksnimi aritmetičnimi izračuni in obdelavo signalov. V tej raziskavi je predstavljeno novo vezje SPM, ki temelji na QCA, za optimizacijo učinkovitosti vezja množitelja in izboljšanje celotne zasnove. Pred...

“…By scaling CMOS transistors, some problems, such as high leakage current and low threshold voltage, emerge. Therefore, alternative technologies, such as CNTFET, FINFET, and Quantum-dot cellular automata (QCA), have been proposed to resolve these problems [1][2][3][4][5][6][7][8]. One of the alternative technologies that have received more attention is QCA technology.…”

Quantum-dot cellular automata (QCA) technology is one of the candidate technologies to replace CMOS in multi-valued logic (MVL) circuit designs, to overcome the problems of binary systems. One of the advantages of MVL systems is that they can process more information. Some techniques are essential to simulate and evaluate new multi-valued designs and their performance. This article introduces a new software platform for simulating Quaternary QCA (QQCA) circuits that can be run on computers on Windows and Linux computers is powerful and can run simulations with high accuracy. The presented tool provides the results in two formats. The first format is waveform and the second one is truth table . The presented software has a user-friendly interface that allows users to easily implement their QQCA circuits. Furthermore, the electrostatic energies for all cases in which the basic gates assume four values are determined and the step-by-step simulation process is described. The basic NOT, AND, and OR gates have already been simulated and validated by the relevant software.
