Unroll3qOrMore

class qiskit.transpiler.passes.Unroll3qOrMore(*args, **kwargs)

기반 클래스: TransformationPass

Recursively expands 3q+ gates until the circuit only contains 2q or 1q gates.

Initialize the Unroll3qOrMore pass

매개변수:

• target (Target) – The target object representing 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_gates are 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 target are specified only the target will be used for checking which gates are supported.

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).

Methods

name()

Return the name of the pass.

run(dag)

Run the Unroll3qOrMore pass on dag.

매개변수:

dag (DAGCircuit) – input dag

반환:

output dag with maximum node degrees of 2

반환 형식:

DAGCircuit

예외 발생:

QiskitError – if a 3q+ gate is not decomposable
