1Bloch Sphere
|ψ⟩
Apply a gate
Small rotations about the axes
2|a|² + |b|² = 1
What should move when you drag? Since |a|² + |b|² = 1, the other magnitude adjusts automatically.
3x² + y² = 1
Drag the blue point or choose an angle θ:
A measurement gives |0⟩ with probability … and |1⟩ with probability ….
