| Abstract | An important property of reversible circuits is that they can reduce the energy consumption which is now a big problem for the advanced circuit design. If a circuit is reversible, it can reduce the energy consumption caused by information loss. The tabulation method is more efficient than other simplification methods for combination logic circuits. But the classical tabulation method is not directly applicable to reversible circuits because the basic logic gates, except the NOT gate, are not reversible gates. In this paper, we propose a method to solve the problem so that the tabulation method can be applied to the reversible circuit synthesis. Our algorithm provides a systematic method to simplify the reversible circuit. This can produce the resulting expression in exclusive-sum form and transform it into a final reversible circuit with lower quantum cost. Moreover, we can realize permutations to be reversible circuits with lower quantum cost and without unnecessary garbage bits. We can also convert irreversible circuits by adding qubits to make the circuits reversible. The experimental results show that the average saving in quantum cost is 15.82% compared with previous approaches. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
