Classification: CPC H  G | IPC G  H

Claim 0:
1. A fault tolerant and error correction decoding method for a quantum circuit, applicable to a computer device, the method comprising:
obtaining actual error syndrome information of a quantum circuit by performing a noisy error syndrome measurement on the quantum circuit using a quantum error correction (QEC) code;
decoding the actual error syndrome information to obtain a logic error class and perfect error syndrome information, which correspond to the actual error syndrome information, the logic error class being a class obtained through mapping of an error occurring in the quantum circuit and the perfect error syndrome information being obtained by performing a noise-free error syndrome measurement on the quantum circuit; and
determining error result information of the quantum circuit based on the logic error class and the perfect error syndrome information, the error result information being indicative of a data qubit in which an error occurs in the quantum circuit and a corresponding error class.
