How do photons become entangled
WebOct 9, 2024 · Add a comment. 1. Entanglement cannot be used to transfer information faster than light, unfortunately. There is not a time limit to entanglement between two photons. Some pairs of photons emitted billions of years ago are still entangled because neither of the entangled members of the pair have ever interacted with anything. WebJan 18, 2024 · There are different ways in which polarization of two photons can be entangled. For maximally entangled states, these different ways are represented by the Bell states. The one case that you represent here is where their spin is anti-correlated, but it could just as well have been correlated.
