Hello, I am doing a small presentation on Quantum Cryptology this next week, and need a little help relating HUP and polarization of photons.
I understand that when you polarize a photon on a basis of say 45* the photon simultaneously exist in both the horizontal and vertical polarizations at the same time. With that said, I really need someone to break down HUP with polarization...
What I don't get: When you vertically polarize a photon (light) how you can set a second filter to polarize it at 45* but not 0* (horizontally, where it will be fully absorbed).
