Abstract: Disclosed is an operating method of a computing device. The operating method of a computing device includes generating quantum mapping basis information based on a fault-tolerant constraint, generating quantum circuits and initial qubit mappings by performing a quantum circuit mapping as much as the number of times based on the fault-tolerant constraint, the quantum mapping basis information, and different random initial qubit mappings, and selecting one quantum circuit and one initial qubit mapping from among the quantum circuits and the initial qubit mappings, respectively.
