Hi @adri
Welcome to the forum.
Let’s take a step back and think about it.
You are in the right track. However, the hint says to think about what to do with the inconclusive cases. In what cases for m_bomb is the experiment inconclusive? Look at the diagram and apply the conditional operator for those cases.
Then, after the qml.cond, imagine that you are feeding that into another round of interaction with the bomb and so on. As though you were repeating the rest of the first cycle of operations.
Let me know if this was helpful or I can clarify further.
Thanks!
