Research ArticleOpen accessIn the keywordsA Novel Fault-Tolerant Majority Gate Architecture for Robust Operation in QCA-Based Nano CircuitsAmi Patel, Vrushank Shah, Dipti KhurgeQuantum Dot Cellular Automata (QCA) is one of the promising alternatives to the traditional CMOS technologies for next-generation nanocomputing, which can be integrated at a higher density and has a higher possibility of low power consumption. Fabrication defects, environmental noise, and fault tolerance, especially in larger circuits, are challenging for practical implementation of QCA circuits. A new Fault-Tolerant Majority Gate … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,194 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Analysis of Adders using Nanotechnology Based Quantum dot Cellular AutomataS. Karthigai Lakshmi, G. AthishaProblem statement: The area and complexity are the major issues in circuit design. Here, we propose different types of adder designs based on Quantum dot Cellular Automata (QCA) that reduces number of QCA cells and area compare to previous designs. The quantum dot cellular automata is a novel computing paradigm in nanotechnology that can implement digital circuits with faster speed, … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 7,311 accessesView PDFCite
