Multiple-control Toffoli gates are basic building blocks for reversible and quantum circuits. 3-bit Peres gate can be considered as a pair of 3-bit and 2-bit Toffoli gates, which can be implemented with fewer elementary quantum gates (what defines a metric called quantum cost) than the total number of elementary quantum gates required by each of Toffoli gates implemented separately. Due to this property,...
This paper reports on a method of the construction of new difficult benchmarks for reversible logic synthesis. It is shown how to extrapolate 3- and 4-variable reversible functions implemented by gate count minimal circuits having regular structure. In this way sequences of reversible functions of an arbitrary number of variables have been constructed for which we have built minimal circuits implementing...
Optimal synthesis of reversible circuits is a very hard task. In 2010, a method and a tool of practical usage for finding optimal circuits built from multi-control Toffoli gates for any 4-bit reversible specification were finally developed. In 2011 we published an extension to the algorithm, which allows to reduce the quantum cost of the resulting circuits. In this paper we present another extension...
Recently, one of the main criteria used to evaluate reversible circuit designs is quantum cost. In this paper, an approach to reducing quantum cost of small-width reversible circuits is presented. Using our tool we have shown that for known benchmarks as well as designs taken from recent publications it is possible to obtain substantial savings in quantum cost (35% on average for 4-input benchmarks)...
