Implementation of Area Efficient Fredkin Gate for Compact Reversible QCA Circuit

摘要

One of the greatest challenges in quantum computing is constructed logic gates with useful processing circuits. It is difficult to make more complex operations in quantum computers. These problems are solved by classical Fredkin gate. In this paper, one of a reversible logic new efficientdesign of Fredkin gate is presented. Fredkin gate is the only reversible gate which supports both conservative and reversible logic and also having less quantum delay. Therefore, proposed design has the capability to decrease the power dissipation which is the main requirement in low powerVery-large-scale integration design. The main target of proposed design is to reduce quantum cost, the extent of the circuits and the number of garbage outputs. The proposed design leads to the reduction of power consumption and standard form in realization for complex circuits compared withprevious logic circuits. These structures are designed with QCADesigner simulator and simulation results are examined.
