TrivialLayout
class TrivialLayout(*args, **kwargs)
Bases: qiskit.transpiler.basepasses.AnalysisPass
Choose a Layout by assigning n circuit qubits to device qubits 0, .., n-1.
A pass for choosing a Layout of a circuit onto a Coupling graph, using a simple round-robin order.
This pass associates a physical qubit (int) to each virtual qubit of the circuit (Qubit) in increasing order.
Does not assume any ancilla.
TrivialLayout initializer.
Parameters
coupling_map (Coupling) – directed graph representing a coupling map.
Raises
TranspilerError – if invalid options
Methods
name
TrivialLayout.name()
Return the name of the pass.
run
TrivialLayout.run(dag)
Run the TrivialLayout pass on dag.
Parameters
dag (DAGCircuit) – DAG to find layout for.
Raises
TranspilerError – if dag wider than self.coupling_map
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).
