PulseGates#

class qiskit.transpiler.passes.PulseGates(*args, **kwargs)[소스]#

기반 클래스: CalibrationBuilder

Pulse gate adding pass.

This pass adds gate calibrations from the supplied InstructionScheduleMap to a quantum circuit.

This pass checks each DAG circuit node and acquires a corresponding schedule from the instruction schedule map object that may be provided by the target backend. Because this map is a mutable object, the end-user can provide a configured backend to execute the circuit with customized gate implementations.

This mapping object returns a schedule with “publisher” metadata which is an integer Enum value representing who created the gate schedule. If the gate schedule is provided by end-users, this pass attaches the schedule to the DAG circuit as a calibration.

This pass allows users to easily override quantum circuit with custom gate definitions without directly dealing with those schedules.

References

Create new pass.

매개변수:

  • inst_map – Instruction schedule map that user may override.

  • target – The Target representing the target backend, if both inst_map and this are specified then it updates instructions in the target with inst_map.

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).

Methods

get_calibration(node_op, qubits)[소스]#

Gets the calibrated schedule for the given instruction and qubits.

매개변수:

  • node_op (Instruction) – Target instruction object.

  • qubits (List) – Integer qubit indices to check.

반환:

Return Schedule of target gate instruction.

예외 발생:

TranspilerError – When node is parameterized and calibration is raw schedule object.

반환 형식:

Schedule | ScheduleBlock

name()#

Return the name of the pass.

run(dag)#

Run the calibration adder pass on dag.

매개변수:

dag (DAGCircuit) – DAG to schedule.

반환:

A DAG with calibrations added to it.

반환 형식:

DAGCircuit

supported(node_op, qubits)[소스]#

Determine if a given node supports the calibration.

매개변수:

  • node_op (Instruction) – Target instruction object.

  • qubits (List) – Integer qubit indices to check.

반환:

Return True is calibration can be provided.
