It's a very interesting question. How does 'photons' transmit information? They have a momentum, a 'spin', and 'energy', as far as I know.

Think you can split it in two parts actually, one is the wave description, but that one falls apart at the moment of annihilation to me, as that is a 'photon' interaction to me. To me it has to be, as it is as local as can be, and to get to a wave picture you need to introduce frames of reference communicating this wave you describe.

So locally I would define the communication as carried by 'photons'. How do they do it?

To add to 'spin'. Normally we define it as being of two possible values only, 'up or down', but is that correct or is it a result of the way we do the experiments? If it's possible for this spin to have more values, would that add to the information? And if so, how does it then get read by the sink? Should be possible, if so, to construct a experiment testing it, shouldn't it?

There is also naturally the aspect of synthesizing out a information over time, by our brains. This one assumes a constant called the 'arrow of time', locally equivalent for anything inside the observable universe we define. As long as this arrow is a (local) constant shared throughout a universe you could assume that it is not the single piece of information described by each photon that makes up the 'frozen image' your brain construct but a 'string of photons' giving you that still image that your brain, using the arrow once again, then further strings together into a moving picture.
