Design of Digital Adder Using Reversible Logic

Reversible logic circuits have promising applications in Quantum computing, Low power VLSI design,\ud Nanotechnology, optical computing, DNA computing and Quantum dot cellular automata. In spite of them\ud another main prominent application of reversible logic is Quantum computers where the quantum devices are\ud essential which are ideally operated at ultra high speed with less power dissipation must be built from reversible\ud logic components. This makes the reversible logic as a one of the most promising research areas in the past few\ud decades. In VLSI design the delay is the one of the major issue along with area and power. This paper presents\ud the implementation of Ripple Carry Adder (RCA) circuits using reversible logic gates are discussed
