Hi friends,
good work here. Going in a good direction. For the sake of improving, do double check the correctness of your circuit. The CNOT with multiple target decomposition that you re-used from the GHZ tutorial only works if the other qubits start at the |0> state. But QFT comes as a sub-routine and has to be deployable for arbitrary states.

The correct decomposition (also called a, in this case, CNOT fanout) goes as follows:

(more details on Fig 2 of https://arxiv.org/html/2408.03064v1)

Other than that, good luck debugging!
Don't forget your learning objectives!
