Bug Discovery in Codercise I.11.4 of the Codebook

By mistake, I used the PauliX gate instead of the PauliZ in circuit 2, resulting in an incorrect graph. However, the Codebook’s answer still indicates “correct”.

Thank you @JH_S for spotting this!

Seems like we have a test case to fix here :sweat_smile:

Cheers,

Alvaro
