QONSystemMetric

Module: iqm.station_control.client.qon

class QONSystemMetric(locus_str, method, metric)

Bases: QONMetric

QON representing a system quality metric.

Has the form metrics.{method}.{locus_str}.{metric}.

Can parse/represent e.g. the following metrics:

metrics.ghz_state.QB1__QB2.coherence_lower_bound

method: ghz_state locus_str: QB1__QB2 metric: coherence_lower_bound

Subclasses implement parsing and string representation for specific methods.

Attributes

method	Name of the method by which the metric was measured.
metric	Measured metric.
locus_str	Sequence of names of QPU components to which the observation applies, encoded into a string.

Methods

Parameters:

• locus_str (str)

• method (Annotated[str, FieldInfo(annotation=NoneType, required=True, metadata=[_PydanticGeneralMetadata(pattern='^[A-Za-z_][A-Za-z0-9_]*$')])])

• metric (Annotated[str, FieldInfo(annotation=NoneType, required=True, metadata=[_PydanticGeneralMetadata(pattern='^[A-Za-z_0-9][A-Za-z0-9_]*$')])])
