A modified Transformation-Template based Synthesis using FREDKIN/SWAP Gates in Reversible Circuits (original) (raw)
2018, Procedia Computer Science
Reversible logic computing is an emerging research area due to its high-speed computing abilities and generating the lossless information. Due to the ability of reverse operation and high-speed computing performance, reversible computation is considered as a future alternative to the conventional computing. The rapid progress of reversible computation in the current scenario, the reversible circuit is the way to solve this type of computation. Moreover, the reversible circuit computation is the higher level abstraction of the quantum circuit. The synthesis design of these circuits is an important aspect in the current literature. In this paper, we present our work in the field of synthesis design of a reversible circuit. In this work, we propose a modified transformationbased synthesis design using the FREDKIN/SWAP gate to reduce the quantum cost and minimizing the number of gates. To obtain this synthesis design approach, we have introduced some new templates which are defined by rules of replacing the k-CNOT/FREDKIN/SWAP gates using a template matching approach. Here, we are considering only k-CNOT (k ≥ 1), FREDKIN and SWAP based gate in our templates. Finally, we provide our experimental results based on different benchmark reversible circuits. The experimental result has shown that the number of quantum cost and gate count are reduced using the FREDKIN/SWAP gate in the transformation-based approach with the help of proposed templates.
