# RemoveBarriers¶

class RemoveBarriers(*args, **kwargs)[Quellcode]

Bases: qiskit.transpiler.basepasses.TransformationPass

Return a circuit with any barrier removed.

This transformation is not semantics preserving.

Example

from qiskit import QuantumCircuit
from qiskit.transpiler.passes import RemoveBarriers

circuit = QuantumCircuit(1)
circuit.x(0)
circuit.barrier()
circuit.h(0)

circuit = RemoveBarriers()(circuit)
circuit.draw()

Methods

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