ABSTRACT

 At present days , reversible logic circuits have many applications in the field of  optical information processing, digital signal processing , nano technology and  quantum computing . Reversible logic plays an important role when computations with minimum energy dissipation are considered. The  purpose of designing reversible logic is to decrease the number of area, power, garbage outputs , constant inputs, quantum cost,  reversible gates, delay and hardware complexity . This paper reveals a review on some reversible logic gates, which is useful in designing more complex systems having reversible circuits and can do execution of  more complex operations using quantum computers. In upcoming days  digital technology will be using reversible logic gates in order to reduce the propagation delay and power consumption as it  provides negligible loss of information in the circuit.

Keywords: Reversible Gate, Garbage output, quantum cost, Reversible logic, Power dissipation
