The quantum dot cellular automata is one of the various nanostructure based paradigms that have been proposed to overcome the limits being faced by the existing CMOS technology. The prevalent building block for QDCA has been the majority voter which is not functionally complete as it lacks conditional inversion. In an earlier work we have proposed a new architecture for a NAND/NOR based universal gate and shown it to be more compact as compared to the earlier proposed AOI and NNI structures. Landauer's limit places a lower bound on energy dissipation in conventional circuits which may be overcome by reversible computing. In this paper we have realized several standard reversible gates using our structure and shown those to be much more compact compared to the prevalent Majority voter based design. We have also proposed a new Universal reversible gate and made a comparative study with the popular PERES gate.
