ApplyLayout
ApplyLayout(*args, **kwargs)
Bases: qiskit.transpiler.basepasses.TransformationPass
Transform a circuit with virtual qubits into a circuit with physical qubits.
Transforms a DAGCircuit with virtual qubits into a DAGCircuit with physical qubits by applying the Layout given in property_set. Requires either of passes to set/select Layout, e.g. SetLayout, TrivialLayout. Assumes the Layout has full physical qubits.
Methods
name
ApplyLayout.name()
Return the name of the pass.
run
ApplyLayout.run(dag)
Run the ApplyLayout pass on dag.
Parameters
dag (DAGCircuit) – DAG to map.
Returns
A mapped DAG (with physical qubits).
Return type
Raises
TranspilerError – if no layout is found in property_set or no full physical qubits.
Attributes
is_analysis_pass
Check if the pass is an analysis pass.
If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.
is_transformation_pass
Check if the pass is a transformation pass.
If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).
