Optimize1qGates

class Optimize1qGates(*args, **kwargs)

Bases: qiskit.transpiler.basepasses.TransformationPass

Optimize chains of single-qubit u1, u2, u3 gates by combining them into a single gate.

Optimize1qGates initializer.

Parameters

• basis (list[str]) – Basis gates to consider, e.g. [‘u3’, ‘cx’]. For the effects of this pass, the basis is the set intersection between the basis parameter and the set {‘u1’,’u2’,’u3’, ‘u’, ‘p’}.

• eps (float) – EPS to check against

Methods

compose_u3	Return a triple theta, phi, lambda for the product.
name	Return the name of the pass.
run	Run the Optimize1qGates pass on dag.
yzy_to_zyz	Express a Y.Z.Y single qubit gate as a Z.Y.Z gate.

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).
