A novel single layer full-adder in Quantum-dot Cellular Automata (QCA) 

, 2022
Abstract Quantum-dot Cellular Automata (QCA) is a new technology for designing digital circuits in nanoscale. The design of a QCA circuit is radically different from the conventional digital design due to its unique characteristics at both the physical and logical levels. Quantum-dot Cellular Automata is not a physical implementation yet, it is
