Design And Simulation of Tree Multiplier using Reversible logic Gate

Reversible logic is one of the most important issue at present time and also it has different areas for its application, such as quantum computing, low power CMOS, DNA computing, nanotechnology, cryptography, digital signal processing (DSP), communication, computer graphics, quantum dot cellular automata. Realization of quantum computing without implementation of reversible logic is not possible. with the significance to decrease depth of the circuits The reversible logic is designed, the number of garbage outputs and quantum cost. This paper describes the basic reversible logic gates. These reversible logic gates are used for designing of more complex system having reversible circuits as a primitive component and which can execute more complicated operations using quantum computers. The Designing of reversible logic gate using tanner tool is shown in the paper. Also reversible logic gate is design using pass transistor logic. And design of 4*4 multiplier is shown in this paper, also design of 5*5 multiplier is shown in this paper. Output of 4*4 multiplier and 5*5 is given in this paper.
