Abstract: Provided is a processing method, device and system for quantum cloud computing and a medium. The method includes: obtaining the number of historical interruptions of an X-th commit instruction when the XM-th commit instruction needs to be sent, where the X-th 5 commit instruction is obtained based on a subtask of a target task to be executed by a quantum computer; obtaining a calibration instruction based on historical interruption feature information of the XM-th commit instruction when confirming that the number of historical interruptions of the XM-th commit instruction is greater than a preset threshold, where the calibration instruction is used to instruct the quantum computer to perform parameter calibration and/or noise 0 processing; sending the calibration instruction to the quantum computer; and sending at least one run instruction contained in the X-th commit instruction to the quantum computer when determining that the quantum computer completes execution of the calibration instruction.
