Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality

[Greg Bernhardt]

TL;DR Summary

Entangled photons violate the Bell-CHSH inequality because quantum mechanics gives discrete pass/fail outcomes rather than smooth classical averages. Their correlations exceed what any hidden-variable theory allows, reaching the maximum quantum limit and revealing nonlocal behavior. - ChatGPT5

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.

In her YouTube video Bell’s Theorem Experiments on Entangled Photons, Dr. Fugate shows how polarization-entangled photons violate Bell’s inequality. In this Insight, I will use quantum information theory to explain why such entangled photon-polarization qubits violate the version of Bell’s inequality due to John Clauser, Michael Horne, Abner Shimony, and Richard Holt known as the Clauser-Horne-Shimony-Holt (CHSH) inequality...

Who wrote that summary? It's spot on, yet concise. I've presented this idea more generally at conferences and seminars around the world and published it in a book, papers and blogs, but whoever wrote this summary did a better job :-)

Hey, summarization is actually one thing it's qualified to do

I was banned from this forum just for posting a link to an article I wrote using ChatGPT, which I thought was well written. I did not see any obvious. Nobody said there was an error, but if hypothetically someone was claiming there was an error, you could have pointed it out instead of immediately banning me from the forum just because I posted a link to something written by ChatGPT. If I was banned from Physics Forums just for posting a link to a ChatGPT written article when why isn't Greg Bernhart banned from Physics Forums for posting a ChatGPT written article?

Here are two of the rules that you accepted and agreed to follow by joining and posting on Physics Forums:

ChatGPT and AI-generated text

• Posting AI-generated text without attribution is categorically disallowed and will lead to a warning and an eventual permanent ban with continued use.
• Answering a science or math question with AI-generated text, even with attribution, is not allowed. AI-generated text apps like ChatGPT are not valid sources.

Your posts clearly violated both rules.

why isn't Greg Bernhart banned from Physics Forums

Because he is the owner of Physics Forums.

@Jeffery you do make a good point and I should have attributed the summary. I will do that now and in the future.
