QONGateMetric

class QONGateMetric(method, locus_str, metric, gate, implementation, suffixes=<factory>)

Bases: QONMetric

QON representing a gate quality metric.

Has the form metrics.{method}.{method_specific_part}.

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

metrics.ssro.measure.constant.QB1.fidelity:par=d1:aaa=bbb

method: ssro gate: measure implementation: constant locus_str: QB1 metric: fidelity suffixes: {“aaa”: “bbb”, “par”: “d1”}

metrics.ssro.measure.constant.QB1.fidelity

method: ssro gate: measure implementation: constant locus_str: QB1 metric: fidelity suffixes: {}

metrics.rb.prx.drag_crf.QB4.fidelity:par=d2

method: rb gate: prx implementation: drag_crf locus_str: QB4 metric: fidelity suffixes: {“par”: “d2”}

Module: iqm.station_control.client.qon

Attributes

suffixes	Suffixes defining the metric further (if any).
gate	Name of the gate/quantum operation.
implementation	Name of the gate implementation.
method
locus_str	Sequence of names of QPU components on which the gate is applied, or on which the experiment is run, encoded into a string.
metric	Measured metric.

Methods

Parameters:

• method (str)

• locus_str (str)

• metric (str)

• gate (str)

• implementation (str)

• suffixes (dict[str, str])

gate: str

Name of the gate/quantum operation.

implementation: str

Name of the gate implementation.

suffixes: dict[str, str] = FieldInfo(annotation=NoneType, required=False, default_factory=dict)

Suffixes defining the metric further (if any).

classmethod _parse(method, method_specific_part)

Parse a metric observation name that includes a gate and an implementation.

Parameters:

• method (str) – The method name.

• method_specific_part (str) – The method-specific part of the metric observation name.

Returns:

Parsed metric name.

Raises:

ValueError – Observation name is malformed.

Return type:

QONGateMetric
