Abstract: A control pulse generation method, a system, a device and a storage medium are provided, which are related to the field of quantum computing. The method includes: acquiring a system Hamiltonian; acquiring an initial control pulse of a quantum logic gate included in a parameterized quantum circuit to obtain an initial pulse sequence for a gate sequence formed for all the quantum logic gates in the parameterized quantum circuit, which is obtained through simulation based on the system Hamiltonian; acquiring system state information of the quantum system obtained after applying the initial pulse sequence to the target quantum hardware device; adjusting a parameter of the parameterized quantum circuit based on a relationship between the system state information and target state information needed to be achieved by the target quantum control task, to adjust a pulse parameter of the initial pulse sequence to obtain a target pulse sequence.
