Capitalize Bloch outside variable names.

Also, why are we using Bloch vectors here? I guess bloch_vector_from_state_vector is convenient for comparing individual qubits out of the entire state, but it still feels kind of roundabout.

[augustehirth]

That's exactly why. It's a slight trade-off of adding more code so that there is more direct printed content indicating that the two qubits are in the same state. The final_state_vectors by themselves are not directly comparable and just showing counts from results could obfuscate the point because different states could produce the same results. Is there a better way of seeing the state of a single qubit?

[95-martin-orion]

You're probably right about it being the clearest comparison - I couldn't find a better alternative in a quick search. Let's keep the code as-is but clarify why we're using Bloch vectors in the comment.

Ready to merge once the clarifying comment on Bloch vector usage is added.
