Wave function

The gold curve is amplitude. The blue fill is probability density. Move the control and watch the packet spread while total probability stays finite.

Interference

Center intensity is 1.00 because the paths arrive in phase.

Bloch sphere

P(0)=0.38, P(1)=0.62. The point on the sphere is a state, not a hidden classical bit.
