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.
