Abstract: The present disclosure provides a quantum entangled state processing method and apparatus, a device, a storage medium, and a product, which are related to a field of quantum calculation. The specific implementation scheme includes: determining n initial quantum states to be processed; determining at least two nodes associated with the initial quantum state, wherein the first qubit is positioned at a first node of the at least two nodes, and the second qubit is positioned at a second node of the at least two nodes; acquiring at least one first parameterized quantum circuit required by the first node and at least one second parameterized quantum circuit required by the second node matched with a preset processing scenario; controlling, based on an initial quantum operation strategy, the first node to perform a local quantum operation to obtain a first measurement result, controlling the second node to perform a local quantum operation to obtain a second measurement result; obtaining an output quantum state meeting a preset requirement of the preset processing scenario at least based on the first measurement result and the second measurement result. In this way, the processing of a quantum entangled state is realized.

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.
