# RZXCalibrationBuilderNoEcho¶

class RZXCalibrationBuilderNoEcho(backend)[source]

Bases : qiskit.transpiler.passes.scheduling.calibration_creators.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.

Paramètres

backend (<module 'qiskit.providers.basebackend' from '/opt/hostedtoolcache/Python/3.8.12/x64/lib/python3.8/site-packages/qiskit/providers/basebackend.py'>) – Backend for which to construct the gates.

Lève

QiskitError – if open pulse is not supported by the backend.

Methods

 get_calibration Builds the calibration schedule for the RZXGate(theta) without echos. name Return the name of the pass. rescale_cr_inst type instruction Play run Run the calibration adder pass on dag. supported type node_op DAGNode

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).
