A Space-Efficient Universal and Multi-Operative Reversible Gate Design Based on Quantum-Dots

Abstract

Because of the high speed, low-power consumption, low latency and possible use at the atomic and molecular levels, Quantum-dot Cellular Automata (QCA) technology is one of the future nanoscale technologies that can replace the present transistor-based technology. For the purpose of creating QCA circuits, reversible logic can be regarded as an appropriate candidate. In this research, a new structure for multi-operative reversible designs is suggested. The Saeid Nima Gate (SNG), proposed in this research study, is a brand-new, incredibly effective, multi-operative, universal reversible gate implemented in QCA nanotechnology employing both majority and inverter gates. Reversible gates, also known as reversible logic gates, are gates that have n inputs and n outputs, which is an equal number of inputs and outputs. The amount of energy lost during computations will be reduced if the numbers of inputs and outputs are identical. The proposed gate is modified and reorganized to optimize further, employing exact QCA cell interaction. All fundamental logic gates are implemented using it to demonstrate the universality of the proposed SNG. Reversible logic has advanced, and as a result, our suggested solution has a lower quantum cost than previously reported systems. The suggested design is simulated using the QCADesigner-E tools.
