How Would Electron Entanglement Affect Photon Emission

Click For Summary
SUMMARY

The discussion centers on the implications of electron entanglement on photon emission, specifically regarding the entanglement of emitted photons and their polarization. When a pair of spin-entangled electrons absorb and subsequently release photons, the resulting photons are likely to be entangled with each other and with the electrons. The relationship between photon spin and polarization is clarified, indicating that photons, being spin-1 particles, are typically entangled via polarization rather than spin. The coupling of photons to the entangled state of electrons plays a crucial role in determining the characteristics of the emitted photons.

Suppose you have a pair of electrons in the same quantum state, and are thus spin entangled, and they absorb a pair of photons and release them at the same time. How would this affect the photons? Would the photons be entangled? Would it affect the photon spin, and if so, how would it affect the photon polarization? On a related note, why can't photons be entangled via spin, but rather polarization, or is saying they are spin- or polarization-entangled, essentially the same?

Essentially the same. Photons are spin-1 particles.
 
Would being emitted from spin entangled electrons affect their spin? Would the photons be polarization-entangled?

I think the resulting photons would be entangled with each other and also with the two electrons. Not sure about polarization.
 
You need to give far more detail on the scenario you've proposed. All you said is:

How do they absorb them? You've only specified their initial state, but by absorbing two photons they've presumably gone to some excited state(s) and back. The resulting physics depends very strongly on how the photons couple to this entangled state and what their intermediate state (and its coupling to the photon) is.
