in the quantum-classical hybird neural network, to avoid time consuming, I can not give the qubit a great value.
when I put 3 observables on one wire and put measurement process on, I get some error as below:
it says Only observables that are qubit-wise commuting Pauli words can be returned on the same wire.
when I take the middle observable as qml.Identity, same error happens.
are there some proper qubit-wise commuting observables in pennylane?
or some other methods broaden the output dimension beyond nqubits?
