Abstract — Reversible logic is one of the most important issue at present time and it has different areas for its application. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs This paper represents an another approach to realize 4 bit 2’s complement adder subtractor by using reversible logic gates like Feynman Gate, DKG gate and one control line. A also a new reversible gate DKFG is proposed. Keywords—Reversible logic, Basic Reversible Gates, 2’s Complement, Reversible full adder, Reversible full sub-

The power dissipation problems which occur in the computational operations of a computer can be avoided by replacing the irreversible structures by reversible structures. The reversible logic gates are used for the construction of important arithmetic and logic units of quantum computers. This has led many researchers to take reversible logic very seriously. In this proposal a new reversible logic gate called BVMF gate is designed which is useful for the realization of multi functions required for building important computational blocks of quantum computers.

Reversible logic is one of the most important issues at present time and it has different areas for its application. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs. A new reversible gate COG is proposed in this paper. This paper also represents an ease implementation of 4 –bit arithmetic circuit for 8 operation by using the reversible COG gate .
