    Abstract: The present disclosure provides a quantum pulse determining method, apparatus, device and readable storage medium, where basic pulses corresponding to basic logic gates are set in advance, the method including: when manipulating a qubit according to a quantum logic gate, 5 splitting the quantum logic gate to obtain sub-logic gates; and searching for sub-pulses corresponding to the sub-logic gates among the basic pulses, and manipulating the qubit according to the sub-pulse. According to the solution provided by the present disclosure, basic pulses are set in advance in the method, apparatus, device and readable storage medium provided by the embodiments. When a qubit is to be manipulated, the quantum logic gate to be 0 used can be split into multiple sub-logic gates, and then sub-pulses corresponding to the sub logic gates are searched for among the basic pulses. Thus, sub-pulses that are read can be used directly to manipulate the qubit, which avoids the computing power consumed in generating pulses according to the quantum logic gate, thereby improving an operation speed of the quantum computing system.
