# qiskit.transpiler.passes.Width¶

class Width(*args, **kwargs)[código fonte]

Calculate the width of a DAG circuit.

The result is saved in property_set['width'] as an integer that contains the number of qubits + the number of clbits.

__init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

 Initialize self. Return the name of the pass. run(dag) Run the Width pass on dag.

Attributes

 is_analysis_pass Check if the pass is an analysis pass. is_transformation_pass Check if the pass is a transformation pass.
property 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.

property 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).

name()

Return the name of the pass.

run(dag)[código fonte]

Run the Width pass on dag.
