Abstract

Shrivastava and Dubey M

In this paper, the work of quantum computing and how this technology is helpful in developing future high speed processing reversible logic gates with the help of QCA. This paper describes the various reversible gates in brief by using quantum dot cellular automata. Simulation result and design of Feynman Gate is projected with the use minimum number of quantum cells in multilayer which facilitate the circuit to add more combinatorial circuit in parallel when required corresponding to the Feynman. Several researchers focuses their research on design and synthesis of efficient reversible logic gates. This paper presents the study of quantum computing and combinational circuit of some basic reversible logic gates verified through simulation using QCA designer.
