A wave packet carries information such that when an observation is made, what is received is information, that reveals spin or position etc. All 'particles' at the quantum level can be described by wave packets and the states of those wave packets could be represented by information. The true path of a photon in travelling from A to B without decoherence is unknowable because it was not observed on the way leads one to wonder what it was that was actually travelling. Like Plato's Cave we only get a representation of our 'particle' and the underlying truth is something else (for example information flows in a mathematical model could possibly create the whole shabang) I know there is work being done in this direction but I cannot find it (apart from the late John Wheeler humerously suggesting we may all be in a giant computer). Is there a serious theorem or paper or is it speculation without foundation?
