qml.liealg.check_abelian¶

check_abelian(ops)[source]¶

Helper function to check if all operators in ops commute, i.e., form an Abelian set of operators.

Warning

This function is expensive to compute

Parameters: ops (List[Union[PauliSentence, TensorLike, Operator]]) – List of operators to check for mutual commutation
Returns: Whether or not all operators commute with each other
Return type: bool

Example

>>> from pennylane.liealg import check_abelian
>>> from pennylane import X
>>> ops = [X(i) for i in range(10)]
>>> check_abelian(ops)
True

Operators on different wires (trivially) commute with each other.
