qiskit.transpiler.passes.ALAPSchedule

class ALAPSchedule(*args, **kwargs)

ALAP Scheduling.

ALAPSchedule initializer.

Parameters

durations (InstructionDurations) – Durations of instructions to be used in scheduling

__init__(durations)

ALAPSchedule initializer.

Parameters

durations (InstructionDurations) – Durations of instructions to be used in scheduling

Methods

__init__(durations)	ALAPSchedule initializer.
name()	Return the name of the pass.
run(dag[, time_unit])	Run the ALAPSchedule pass on dag.

Attributes

is_analysis_pass	Check if the pass is an analysis pass.
is_transformation_pass	Check if the pass is a transformation pass.

property 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.

property 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).

name()

Return the name of the pass.

run(dag, time_unit=None)

Run the ALAPSchedule pass on dag.

Parameters

• dag (DAGCircuit) – DAG to schedule.

• time_unit (str) – Time unit to be used in scheduling: ‘dt’ or ‘s’.

Returns

A scheduled DAG.

Return type

DAGCircuit

Raises

TranspilerError – if the circuit is not mapped on physical qubits.
