Design of quantum cost efficient MOD-8 synchronous UP/DOWN counter using reversible logic gate

摘要

The Reversible logic synthesis techniques will be a necessary part of the long-term future of computing due to its low power dissipating characteristic. Today, reversible logic circuits have considerable attention in improving some field like nanotechnology, quantum computing etc. In this paper we proposed the design of MOD-8 synchronous up/down counter with reduced number of quantum cost to implement it using existing reversible logic gates. The quantum cost, number of gates, constant inputs and garbage outputs are respectively are 35, 13, 9 and 12 for the proposed work.
