Abstract

In this paper, we do research on generating unitary matrices for quantum circuits automatically. Here, we consider that quantum circuits are divided into six types, and the unitary operator expressions for each class are offered. Based on this, we propose an algorithm in detail. Then, for quantum logic gates, a faster method to compute the unitary matrix of quantum circuits with the truth table is introduced as a supplement. Finally, we apply the proposed algorithm to different reversible benchmark circuits based on NCT and GT library and provide our experimental results.
