- class RZXCalibrationBuilderNoEcho(*args, **kwargs)[source]¶
Creates calibrations for RZXGate(theta) by stretching and compressing Gaussian square pulses in the CX gate.
RZXCalibrationBuilderNoEchois a variation of the
RZXCalibrationBuilderpass 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
RZXCalibrationBuilderNoEchoonly supports the hardware-native direction of the CX gate.
Initializes a RZXGate calibration builder.
Deprecated since version 0.22.0:
qubit_channel_mappingis deprecated as of qiskit-terra 0.22.0. It will be removed no earlier than 3 months after the release date.
instruction_schedule_map – The
InstructionScheduleMapobject 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
Targetrepresenting the target backend, if both
instruction_schedule_mapand this are specified then this argument will take precedence and
instruction_schedule_mapwill be ignored.
QiskitError – Instruction schedule map is not provided.
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.
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.
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).
