QONMetric

QONMetric#

class QONMetric(method, gate, implementation, locus, metric, suffixes=<factory>)#

Bases: QON

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: QB1 metric: fidelity suffixes: {“aaa”: “bbb”, “par”: “d1”}

metrics.ssro.measure.constant.QB1.fidelity

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

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

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

metrics.ghz_state.QB1__QB2.coherence_lower_bound

method: ghz_state gate: None implementation: None locus: QB1__QB2 metric: coherence_lower_bound suffixes: {}

Module: iqm.station_control.client.qon

Attributes

domain

Type/purpose of the observation.

method

gate

Name of the gate/quantum operation.

implementation

Name of the gate implementation.

locus

Sequence of names of QPU components on which the gate/operation is applied.

metric

Measured metric.

suffixes

Suffixes defining the metric further (if any).
