Abstract: A computer system prepares an initial state of a quantum many-body system through a preparation circuit. The quantum many-body system includes a plurality of qubits. The system processes the initial state through a parameterized quantum circuit (PQC) to obtain an output state of the PQC. The output state of the PQC is used for representing an eigenstate of the quantum many-body system. The system measures the output state of the PQC through a measurement circuit. The system obtains a target parameter index based on a measurement result. The target parameter index is used for determining whether the quantum many-body system is in a many-body localization state. In accordance with a determination that the target parameter index satisfies a condition, the system determines that the quantum many-body system is in the many-body localization state.
