class CommutingObservableGroup(general_observable, commuting_observables)

Set of mutually qubit-wise commuting observables.

__init__(general_observable, commuting_observables)

Methods

__init__(general_observable, ...)

Attributes

general_observable	A single Pauli string that contains all qubit-wise measurements needed to measure everything in commuting_observables.
commuting_observables	Observables that can be measured simultaneously.
pauli_indices	The indices of non-identity Paulis in general_observable.
pauli_bitmasks	A bitmask for each observable in commuting_observables; given an element, each bit corresponds to whether the corresponding entry in pauli_indices is relevant to that observable.
