RZXCalibrationBuilderNoEcho

class RZXCalibrationBuilderNoEcho(*args, **kwargs)[código fonte]

Bases: RZXCalibrationBuilder

Creates calibrations for RZXGate(theta) by stretching and compressing Gaussian square pulses in the CX gate.

The RZXCalibrationBuilderNoEcho is a variation of the RZXCalibrationBuilder pass that creates calibrations for the cross-resonance pulses without inserting the echo pulses in the pulse schedule. This enables exposing the echo in the cross-resonance sequence as gates so that the transpiler can simplify them. The RZXCalibrationBuilderNoEcho only supports the hardware-native direction of the CX gate.

Initializes a RZXGate calibration builder.

Parâmetros
  • instruction_schedule_map – The InstructionScheduleMap object representing the default pulse calibrations for the target backend

  • qubit_channel_mapping – The list mapping qubit indices to the list of channel names that apply on that qubit.

  • verbose – Set True to raise a user warning when RZX schedule cannot be built.

  • target – The Target representing the target backend, if both instruction_schedule_map and this are specified then this argument will take precedence and instruction_schedule_map will be ignored.

Levanta

QiskitError – Instruction schedule map is not provided.

Methods

get_calibration

Builds the calibration schedule for the RZXGate(theta) without echos.

name

Return the name of the pass.

rescale_cr_inst

A builder macro to play stretched pulse.

run

Run the calibration adder pass on dag.

supported

Determine if a given node supports the calibration.

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).
