Hello,
In exercise 2 with corrupted teleportation, I am quite unsure what the condition means by "analyze the standard teleportation protocol". I computed the state of the teleported qubit in Bob's lab and applied the required operators, according to the messages (00, 01, 10, 11). Are we required to compute any probabilities? Or is just showing that the state gets altered in Bob's lab enough (there is always one more term next to the expected teleported state)?
