Abstract: Quantum-dot Cellular Automata (QCA) is attaining worldwide recognition of researchers for its outstanding efficiency in terms of size, energy consumption, and latency as compared to similar nanotechnologies like Complementary Metal-Oxide-Semiconductor (CMOS), a Single Electron Technology (SET), nanowire transistor, Carbon Nanotube Field-Effect Transistor (CNTFET) [1]. The productive implementation of reversible logic is very crucial to carry out quantum computing. Reversible logic reduces the number of gates, quantum cost, and garbage output as information lost during the computation is zero. Reversible logic is an invertible process which means that for each final state of the system, a unique initial state can be determined. There are various implementations of Reversible Logic Gates and Quantum Computing in today’s world, viz., DNA computing, low power CMOS, nanotechnology, etc. This paper provides efficient and modified designs of seven reversible gates using Quantum-dot Cellular Automata.

Keywords: Reversible Logic Gate, Quantum-dot Cellular Automata, Quantum Computing, VLSI.
