HoareOptimizer

class HoareOptimizer(*args, **kwargs)

Bases: qiskit.transpiler.basepasses.TransformationPass

This is a transpiler pass using Hoare logic circuit optimization. The inner workings of this are detailed in: https://arxiv.org/abs/1810.00375

Parameters

size (int) – size of gate cache, in number of gates

Raises

MissingOptionalLibraryError – if unable to import z3 solver

Methods

name	Return the name of the pass.
run	param dag the directed acyclic graph to run on.

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).
