Polarized light; maximum number of disagreements?

Click For Summary

Homework Help Overview

The discussion revolves around the behavior of polarized light, specifically focusing on the concept of disagreements between photon pairs at various angles of polarization. The original poster introduces a comparison of disagreement counts for different angular configurations of polarized photons.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are exploring the definitions and implications of terms like Nmin, N, and Nmax in the context of photon polarization. Questions are raised about the meaning of "maximum number of disagreements" and how it relates to the average number of disagreements. There is also a suggestion to consider the implications of rotating the light.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the original question and the terminology used. Some guidance is offered regarding the existence of a formula for disagreement probability, but there is no consensus on the interpretation of the problem or the specific terms involved.

Contextual Notes

Participants are navigating potential misunderstandings regarding the nature of the photons being discussed, particularly in relation to entangled photons and their polarization states. There is also a mention of the need for explicit definitions and formulas to aid in understanding the problem.

Polarized light and their disagreements

Starting with 2 vertical photons, how can we argue that the maximum number of disagreements and minimum number for +30° and -30° is Nmin(-30°,30°) ≤ N(60°,0°) ≤ Nmax(-30°,30°)? and should we also not rotate the light?

Welcome to PhysicsForums, xb4byish!

I don't follow your question either. However, if by chance you are referring to entangled photons: they cannot be considered as vertically polarized.
 
What are Nmin(-30°,30°), N(60°,0°) and Nmax(-30°,30°)?

What do you mean with maximum number of disagreements? Maximal number of photon pairs where two detectors will see different orientations for both photons? That is just the number of photon pairs. The average number is more meaningful.
 
perhaps its average number of disagreements. But i mean how can we prove the number of disagreements for (60,0) is between the minimum number of disagreements of (-30,0) and the maximum number of disagreements between the maximum number of disagreements of (30,0)
 
I don't understand that question.

There is an explicit formula for the "disagreement probability", you can derive it simply by looking at the 4 different cases. That should help.
