One Qubit: Amplitudes, Probabilities & Normalising a State
This lesson is part of the course
In this lesson
You turn the two amplitudes of eight one-qubit states into measurement probabilities, see that the sign disappears when you square, measure the length of two raw pairs and normalise them into valid states.
