How do photons become entangled
WebThe classical electromagnetic field can then be described as a superposition of plane waves, each with a well-defined frequency, wavevector, and polarization. The classical electromagnetic field can also be obtained by considering the mean value of the quantized electromagnetic field. The mean value of the quantized electromagnetic field is a ...

Her dance ... 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.
