mindquantum.algorithm.compiler.try_merge(father_node: GateNode, child_node: GateNode)

Try to merge two gate nodes.

Following this method, we merge two hermitian conjugated into identity, and also merge two same kind parameterized gate into single parameterized gate.

Parameters

• father_node (GateNode) – the father node want to merge.

• child_node (GateNode) – the child node want to merge.

Returns

• bool, whether successfully merged.

• List[GateNode], the father node after merged.

• GlobalPhase, the global phase gate after merge two given gate node.
