- class Unroll3qOrMore(*args, **kwargs)¶
Recursively expands 3q+ gates until the circuit only contains 2q or 1q gates.
Initialize the Unroll3qOrMore pass
target (Target) – The target object reprsenting the compilation target. If specified any multiqubit instructions in the circuit when the pass is run that are supported by the target device will be left in place. If both this and
basis_gatesare specified only the target will be checked.
basis_gates (list) – A list of basis gate names that the target device supports. If specified any gate names in the circuit which are present in this list will not be unrolled. If both this and
targetare specified only the target will be used for checking which gates are supported.
Return the name of the pass.
Run the Unroll3qOrMore pass on dag.
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.
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).
