circuit_knitting.utils.observable_grouping.ObservableCollection

class ObservableCollection(observables, /)

Collection of observables organized for efficient taking of measurements.

The observables are automatically organized into sets of mutually qubit-wise commuting observables, each represented by a CommutingObservableGroup.

Assign member variables.

Parameters:

observables (PauliList | Iterable[Pauli]) – Observables of interest

__init__(observables, /)

Assign member variables.

Parameters:

observables (PauliList | Iterable[Pauli]) – Observables of interest

Methods

__init__(observables, /)	Assign member variables.
construct_general_observables(...)	Construct the most general observable from each set of mutually commuting observables.

Attributes

groups	List of CommutingObservableGroups which, together, contain all desired observables.
lookup	Get dict which maps each Pauli observable to a list of indices, (i, j), to commuting observables in groups.
