upgrade:
|
|
- |
|
|
:class:`.RZXCalibrationBuilder` and :class:`.RZXCalibrationBuilderNoEcho`
|
|
have been upgraded to skip stretching CX gates implemented by
|
|
non-echoed cross resonance (ECR) sequence to avoid termination of the pass
|
|
with unexpected errors.
|
|
These passes take new argument ``verbose`` that controls whether the passes
|
|
warn when this occurs. If ``verbose=True`` is set, pass raises user warning
|
|
when it enconters non-ECR sequence.
|
|
deprecations:
|
|
- |
|
|
The unused argument ``qubit_channel_mapping`` in the
|
|
:class:`.RZXCalibrationBuilder` and :class:`.RZXCalibrationBuilderNoEcho`
|
|
transpiler passes have been deprecated and will be removed in a future
|
|
release. This argument is no longer used and has no effect on the
|
|
operation of the passes.
