Computational-basis measurement view
Computational-basis measurement probabilities; not a picture of physical space or the complete quantum state.
What changed
The system begins definitely in |00⟩, so measuring now would always produce 00.
Ideal: idealized quantum state behavior for learning.
The center chart shows idealized quantum basis states as bars. In probability view, bar height shows ideal computational-basis measurement probability. In amplitude view, bars show real amplitude above or below a zero axis when the experiment supports that view. This chart shows probabilities in the selected measurement basis. It does not reveal every property of the quantum state. This is an educational visualizer for learning.
