RemoveBarriers
class RemoveBarriers(*args, **kwargs)
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() ┌───┐┌───┐
q: ┤ X ├┤ H ├
└───┘└───┘Methods
name
RemoveBarriers.name()
Return the name of the pass.
run
RemoveBarriers.run(dag)
Run the RemoveBarriers pass on dag.
Return type
DAGCircuit
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).
