lgorithm of Optimizing Quantum Reversible Logic Synthesis

The key of optimizing quantum reversible logic lies in automatically constructing quantum reversible logic circuits with the minimal quantum cost. In order to improve the efficiency of an automatic synthesis and optimization of the reversible logic, a semi-template technique and a fast algorithm was proposed. Template is an efficient optimizing tool, and the semi-template technique can significantly improve the matching efficiency in optimization. R-M synthesis arithmetic is a good iterative method in reversible logic synthesis. Based on the original idea of R-M arithmetic, by constructing an optimal and collision-free Hash function, a new fast algorithm for synthesizing the quantum reversible logic circuits was proposed. This algorithm can construct optimal quantum reversible logic circuits with various types of gates and quantum cost. The experimental results show that to the best of the knowledge in the same testing environment, the results are much better than others.
