Collect2qBlocks

class Collect2qBlocks(*args, **kwargs)

Bases: qiskit.transpiler.basepasses.AnalysisPass

Collect sequences of uninterrupted gates acting on 2 qubits.

Traverse the DAG and find blocks of gates that act consecutively on pairs of qubits. Write the blocks to property_set as a dictionary of the form:

{(q0, q1): [[g0, g1, g2], [g5]],
 (q0, q2): [[g3, g4]]
 ..
 .
}

Based on implementation by Andrew Cross.

Methods

name	Return the name of the pass.
run	Run the Collect2qBlocks 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).
