The Quantum Cost, Garbage Outputs and Constant Input Optimized Implementation of 2:4 Decoder Using Peres Gate

Abstract

This paper presents the quantum cost (QC), garbage output (GO) and constant input (CI) optimized 2:4 decoder using reversible logic gate. The proposed reversible circuit is design using existing reversible logic gate, such as reversible NOT gate, Feynman gate and Peres gate. The proposed decoder can be design using one Peres gate, one NOT gate and four Feynman gate. The QC, GO and CI of the proposed 2:4 decoder is 9, 0 and 2. Which is better w.r.t previously reported work. This is the first reversible 2:4 decoder circuit, which has ‘0’ garbage output. The improvement % of QC, GO and CI are 0 – 74.28 %, 100 % and 33.33 – 75 %.
