Abstract

The quantum compiler reconstructs the quantum circuit written at a high level into native gates operating in quantum hardware. In general, since one quantum gate is replaced by one or more native gates, the circuit will contain significantly more gates than the original quantum circuit. In this paper, we investigate the native gates according to each quantum hardware and analyze how many native gates are added compared to the original quantum circuit. We confirm that IBM, IonQ, Rigetti, and Google generated more native gates than original quantum gates by 5.3 times, 4 times, 5.3 times, and 4 times, respectively. Also, we contribute to further optimization studies for native gate decomposition by revealing the number of native gates with different error rates and latency.
