A photon is emitted and then absorbed. And since a photon travels at the speed of light, time does not exist. So that should mean that a photon is in either a state of emission or a state of absorption. Doesn't that make a photon a type of bit? Furthermore - if there is no time involved then would it be correct to say that a photon ican be in both states (Emission and Absorption) at the same time? Wouldn't it also make a photon a Qbit?
