Abstract:

Reversible logic is the emerging Field nowadays in research area. The aim of this Paper is to realize the different types of combinational And sequential circuits like 1- bit full adder/full sub tractor, 2-bit comparator and d=Latch , D-Flipflop4-bit Johnson counter using reversible logic gates with minimum Quantum cost. There are many reversible logical gates like Feynman ,fredkin , peares , TR , BJN Toffoli gates etc. Reversible logic is nothing butIf the number of inputs are equal to the number of outputs i.e., if there is B-number of inputs and M-number of outputs are present than B=M and there is must be a unique mapping. Between the inputs and outputs. REVERSIBLE LOGIC: Boolean logic is said to be reversible if the set of inputs are equal to the set of outputs.There is unique correspondence between the inputs and outputs.THEME OF REVERSIBLE LOGIC:QUANTUM COST: The implementation cost of a quantum circuits is more precise, Quantum cost is defined as the number of elementary quantum operations needed to realize a gate.

Keywords:

Reversible logic Full adder/full sub tractor, B.SPEED OF COMPUTATION: quantum costed-flip flop, Johnson counter.
