SUMMARY

The discussion centers on the probability amplitudes of polarization, specifically when photons pass through a 45-degree polarizer. When photons are filtered after this polarizer, they exhibit a 50% probability of being vertically or horizontally polarized, analogous to the probability of flipping a coin. Frank confirms that with a large number of photons, the intensity is halved when passing through a vertical polarizer following a 45-degree polarizer. This behavior aligns with classical probability, where repeated trials yield an average probability of 50% for each outcome.

Hello,

I got a question regarding the probability amplitudes of polarization. Say you rotate the polarization amplitudes to 45% so the photons that pass through a filter have 50% probability of vertical or horizontal polarization. Is that 50% probability much like the probability of say throwing coins in the air? Meaning yes the probability of each coin being heads or tails is 50% but upon counting the actual result for each trial of sets of coins you can get more or less of heads or tails, but after many trials it averages out to 50%?

Hi. It seems you are right.
Regards.
 
If it is ordinary classical light with a huge of photons, you would get half intensity with a vertical polarizer after the 45 degree polarizer.
If there is only one photon going through the system for each measurement, then it will be 50% probability for each measurement, like the flipped coin.
