Hi! I have a small, maybe nitpicky comment about the data re-uploading classifier demo page. If we have a 30% probability of being in the |0> state and a 70% probability of being in the |1> state, the associated state quantum state vector isn’t [0.3,0.7] as this isn’t a normalized vector. You would have to take the square root.
Just thought that I would mention this typo since some people might get the wrong idea.
