N2 - Reversible logic is emerging as a promising area of research having its applications in quantum computing, nanotechnology, and optical computing. The classical set of gates such as AND, OR, and EXOR are not reversible. In this paper, a new 4 *4 reversible gate called "TSG" gate is proposed and is used to design efficient adder units. The proposed gate is used to design ripple carry adder, BCD adder and the carry look-ahead adder. The most significant aspect of the proposed gate is that it can work singly as a reversible full adder i.e reversible full adder can now be implemented with a single gate only. It is demonstrated that the adder architectures using the proposed gate are much better and optimized, compared to their counterparts existing in literature, both in terms of number of reversible gates and the garbage outputs.
