The parameter-shift rule | PennyLane Challenges ← the challenge instruction diagram only includes one ring-pattern cnot gate broadcast after the respective rotation gates.
e.g.) (rotation gates with weights[0, :]) → (cnot gate broadcast) → (rotation gates with weights[1, :])
However it seems like the responses are assuming another cnot gate broadcast.
(rotation gates with weights[0, :]) → (cnot gate broadcast) → (rotation gates with weights[1, :]) → (cnot gate broadcast)
This seems like an error. Could you check this?
