Bell-State Entanglement Visualizer

Quantum

$H$ on $q_0$ followed by $\operatorname{CNOT}(q_0\to q_1)$ . Toggling the initialization ports selects which Bell pair is prepared; amplitudes and the correlation index are derived, and a measure button accumulates real Born-rule shots.

Distinguish an entangled Bell state from a classical mixture using outcomes and CHSH.

Prerequisite: none — start here.

predict · then test

After $H$ and CNOT prepare $|\Phi^+\rangle$ , which outcomes can a $Z$ -basis measurement produce?

Commit before the explanation appears. This is a prediction, not a quiz score.

governing model

|\Phi^+\rangle = \dfrac{|00\rangle + |11\rangle}{\sqrt{2}} \;\cdot\; \langle Z \otimes Z \rangle \in [-1, +1]
