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	Return the name of the pass.
run	Run the TrivialLayout pass on dag.

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).
