WebJul 26, 2024 · The (2) bi-photon state is written in a four-dimensional Hilbert space that is the tensor product of the two-dimensional spaces used to describe separately each of the photons in (1). State (2) is a special case of states in which a photon pair can remain. In the general case, there are infinitely many such states, and they can be written down ... Web31. Oddly, polarizing sunglasses provide a quite solid proof that photons are spin 1. That's because if you rotate polarizers by only 90 ∘, you will find that you can break photons down into two mutually exclusive populations of photons. That is geometrically possible only if the particle in question is a vector boson, that is, a spin 1 particle.
