To send the signal, polarizer B is taken away (or put back). Unless polarizer B is there, then 100% of the photons at C get blocked. When B is there, 25% of the photons make it through. Or does photon #1 have to be the one that goes through polarizer B in order for it to have any chance of going through polarizer C?
