There are two polarization filters, A and B.
Polarization filter A has angle of 0° and B has an angle of 30°.
A photon is in superposition, so it doesn't have a definite polarization axis. The likelihood it's passing through a filter is depend on the difference between angle of the polarization filter A and angle of the polarization axis of photon.
But let's say the photon did pass through the filter A, and the photon's axis is now parallell with the filter A's axis (and X axis).
After passing through filter A, is that photon still in a superposition, or does this photon now have a definite polarization axis, or is it still in superposition?
The likelihood P of that photon passing through polarization filter B, is it P = cos^2(30°) = 0.75 ?
