In recent years, reversible logic has been proposed as an emerging technology that can be used in quantum computing, optical computing and nanotechnology. A necessary condition for the reversibility of a computational model is that there should be a unique one-to-one mapping between the inputs and outputs. Conventional gates, however, do not have this capability; thus, reversible gates are designed, and reversible circuits are manufactured by the gates. Measures of quantum cost, the number of constant inputs and the number of garbage outputs are calculated to evaluate the performance of these circuits. In this study, we have decided to design a reversible floating point adder, capable of summing the floating point numbers and minimizing the quantum cost, the number of garbage output and the number of constant input opposed to prior designs.
