In summary, the conversation discusses the probability amplitudes of polarization and how rotating them to 45% results in a 50% chance of vertical or horizontal polarization. This is similar to the probability of throwing coins in the air, where each coin has a 50% chance of being heads or tails. However, with many trials, the results will average out to 50%.

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% probabilty of vertical or horizontal polarization. Is that 50% probabilty much like the probabilty 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.
 

1. What is the probability of polarization amplitudes?

The probability of polarization amplitudes refers to the likelihood or chance that a particle, such as a photon, will have a specific polarization state when measured. It is a value between 0 and 1, with 0 indicating no chance and 1 indicating certainty.

2. How is the probability of polarization amplitudes calculated?

The probability of polarization amplitudes is calculated using the laws of quantum mechanics, specifically the principle of superposition. This takes into account the possible polarization states of a particle and their corresponding amplitudes, and then calculates the probability of measuring a specific state.

3. What factors can affect the probability of polarization amplitudes?

The probability of polarization amplitudes can be affected by various factors such as the angle of polarization, the material the particle is interacting with, and the presence of external fields. These factors can alter the polarization state of the particle and therefore impact its probability of being measured in a specific state.

4. How is the probability of polarization amplitudes used in experiments?

The probability of polarization amplitudes is a crucial aspect of experiments involving particles with a defined polarization state. Scientists use this probability to design and interpret their experiments, and to make predictions about the behavior of particles in different scenarios.

5. What is the significance of Frank's Question in relation to the probability of polarization amplitudes?

Frank's Question, named after physicist Frank Close, refers to the fundamental question of why some particles, such as photons, have a fixed polarization state while others do not. This question highlights the importance of understanding the probability of polarization amplitudes and its role in determining the behavior of particles at a quantum level.
