PROJECT TITLE :
A Post-Synthesis Optimization Technique for Reversible Circuits Exploiting Negative Control Lines
Recent works within the synthesis of reversible logic circuits have been motivated by ever increasing stress on low-power style alternatives, and recent developments in quantum computing. Though most of the synthesis approaches use multiple-management Toffoli (MCT) gates with positive control lines, a few recent works have additionally thought-about MCT gates with negative management lines resulting in better circuit realizations. Some of the works have additionally tried to carry out post-synthesis optimization of given MCT gate netlists with positive management lines, using template matching and similar netlist transformation techniques. However, solely one work is reported that tries to optimize netlists containing negative management MCT gates. This paper proposes an economical optimization technique for MCT gate netlists with each positive and negative management lines, that is based on repeated applications of a small set of pairwise gate merging and replacement rules. Experiments distributed on reversible circuit benchmarks show that it is attainable to achieve important reductions in variety of gates and quantum prices.
