Consider a photon to bean experiment that produces photons in an entangled state such as $1/\sqrt{2}(|{H,H}\rangle+|{V,V}\rangle)$. The photon isphotons are in a superposition of horizontal and vertical polarization, and the way we analyze this is to say that the photon isphotons are in both states at the same time. Though this is odd, I can eventually reconcile it. However, the photonphotons can also be in an entangled state such as $\sqrt{0.2}|H,H\rangle+\sqrt{0.8}|V,V\rangle$. Again, the photon isphotons are in both states at the same time, but do we say that itthey is somehow more in one state than the other? How can we think of this unevenly weighted superposition of states?

Photon in a weighted superposition of states
