we can get tensor measurements by writing something like:
qml.expval(qml.PauliZ(0) @ PauliZ(1))
but is there a way to automate this if I have a variable number of qubits?
Something which might work like:
qml.expval(TENSOR [qml.PauliZ(i) for i in (range(n_qubits))])
this is already possible for local measurements.
If this is something simple that is skipping me right now, I apologise!
