RZXCalibrationBuilderNoEcho¶
- class RZXCalibrationBuilderNoEcho(*args, **kwargs)[source]¶
Bases :
RZXCalibrationBuilder
Creates calibrations for RZXGate(theta) by stretching and compressing Gaussian square pulses in the CX gate.
The
RZXCalibrationBuilderNoEcho
is a variation of theRZXCalibrationBuilder
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. TheRZXCalibrationBuilderNoEcho
only supports the hardware-native direction of the CX gate.Initializes a RZXGate calibration builder.

Methods
Builds the calibration schedule for the RZXGate(theta) without echos.
Return the name of the pass.
A builder macro to play stretched pulse.
Run the calibration adder pass on dag.
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).
