What is the difference between the photon and the phonon ?
Photons are quanta (particles) of the electromanetic field; phonons are collective excitations (quasi particles) of lattices in condensed matter.
What do you have in mind? In QED photons are elementary particles, whereas phonons always consist of underlying structures.Photons can be also interpreted as quasi particles resulting from collective excitations. This is specially true in action-at-a-distance theory electrodynamics, where electromagnetic fields do not exist as material systems.

Do you mean something like a coherent state?
What is AAAD QED? Can you provide some explanations or references? How is this related to the original question which can be interpreted as a question regarding mainstream physics?In field-theoretic QED photons are the particles associated to the EM field. IN AAAD QED, there is not EM field and photons are quasiparticles

Sorry, my answer is approximately 99.999% of the modern picture; but what you propose is not 'the modern picture' at but definitly beyond standard (mainstream) physics. That does not mean that it's wrong, but it's definitly irrelevant for this thread and confusing for the OP.AAAD = Action-At-A-Distance

Because your answer is only a half of the modern picture...

Agree again with you, the American Physical Society, and Reviews of Modern Physics are well-known non-mainstream resources.
