Annotation Quantum dot Cellular Automata (QCA) is an attractive field of nano-technology which offers the various advantages over existing CMOS technology for the development of logic circuits. Contradictory to other technologies which use the voltage levels for logic representation, QCA utilizes the polarization of electrons for representing the binary states in the QCA Cell. Conventional logic circuits are not energy efficient as they are not reversible in nature and hence lead to energy dissipation. Thus there is a need of a serious effort that will provide an efficient paradigm for designing the circuits which does not dissipation the energy and hence will preserve the information. This paper offers the efficient design of various QCA reversible code converters which prove to be efficient in term of cell Area, cell count, total area, latency and complexity. All the proposed reversible code converter designs were simulated and their credibility was successfully verified with the QCADesigner tool
