BlockCollapser

class qiskit.dagcircuit.BlockCollapser(dag)

기반 클래스: object

This class implements various strategies of consolidating blocks of nodes in a DAG (direct acyclic graph). It works both with the DAGCircuit and DAGDependency DAG representations.

매개변수:

dag (Union[DAGCircuit, DAGDependency]) – The input DAG.

예외 발생:

DAGCircuitError – the input object is not a DAG.

Methods

collapse_to_operation(blocks, collapse_fn)

For each block, constructs a quantum circuit containing instructions in the block, then uses collapse_fn to collapse this circuit into a single operation.
