All subclasses of :class:`ControlFlowOp` have an internal attribute, :attr:`~ControlFlowOp.blocks`, which exposes the inner subcircuits used in the different blocks of the control flow. cztj|i||jD]}|jrt ddS)Nz2control-flow blocks cannot contain input variables)super__init__blocksnum_input_varsr)selfargskwargsblock __class__s ]/granary/edev/quantum/lib/python3.11/site-packages/qiskit/circuit/controlflow/control_flow.pyrzControlFlowOp.__init__$s_$)&)))[ Y YE# Y"#WXXX Y Y Yreturntuple[QuantumCircuit, ...]cdS)z{Tuple of :class:`.QuantumCircuit`\ s which may be executed as part of the execution of this :class:`ControlFlowOp`.N)rs rrzControlFlowOp.blocks*rrtyping.Iterable[QuantumCircuit]cdS)aReturn a new version of this control-flow operations with the :attr:`blocks` mapped to the given new ones. Typically this is used in a workflow such as:: existing_op = ... def map_block(block: QuantumCircuit) -> QuantumCircuit: new_block = block.copy_empty_like() # ... do something to `new_block` ... return new_block new_op = existing_op.replace_blocks( map_block(block) for block in existing_op.blocks ) It is the caller's responsibility to ensure that the mapped blocks are defined over a unified set of circuit resources, much like constructing a :class:`ControlFlowOp` using its default constructor. Args: blocks: the new subcircuit blocks to use. Returns: New :class:`ControlFlowOp` with replaced blocks.
