`SProd.terms()` flattens out nested terms #5885

Open astralcai opened 1 week ago

astralcai commented 1 week ago

Context: The .terms() method of Sum, LinearCombination, Hamiltonian, Prod all flatten out any nested terms, but SProd does not. For examples:

>>> coeffs, ops = (2 * (qml.X(0) + qml.Y(0))).terms()
>>> len(ops)
1

Description of the Change: Make it so that SProd flattens out the terms.

Benefits: More consistent behaviour
