The photon and Electromagnetic field

[lightarrow]

I disagree; pure states of polarization can definitely be used to transmit information. QM interpretations only become relevant when dealing with entangled superposed states.

Ok, but to have pure states you have to prepare the photons, so the property "to have a well defined spin component in one direction" cannot be referred to the microscopic object "photon" only, but to the entire experimental setting.

I have created a new thread here[/color] in the Quantum Physics forum of this site to ask further about whether photons "exist" between emission and absorption. I suggest further discussion of quantum mechanical aspects should continue in that thread, and we keep this thread for discussion of any outstanding relativistic issues.
