For a properly prepared entangled state of photons, we expect 100% correlation between detection events when filtered through aligned polarizers. I’m wondering when this was first observed experimentally.
It’s not what you’d expect for ordinary photons. If two photons are prepared in the same polarization state, and fired at a random polarizer, the results are a little different. If I’ve calculated correctly, there’s a 37.5% chance they both get through, a 37.5% chance neither gets through, and a 25% chance that one or the other gets through - a 75% probability of coincidence detection. I think that gives you a correlation of 50%. It’s definitely not 100%.
So I wonder when these anomalous correlations for the entangled state were first observed? This topic came up tangentially in another discussion so I thought I should start a new thread for it.
