I don't think the phonon thing would be involved if it were in a vacuum for both photons.
Of course, photons also strongly interact with lead.

I know that some quantum phenomena demand cool (in some sense) environment, but isn't it so that many things in our homes wouldn't work at all if not quantum physics has a finger in play?
What about a CD-player? Would that device work if only Newtonian physics were available?

Nevertheless, the story that started this thread is, IIUIC, something else. It involves a quantum effect which had, up to now, not been observed under "normal" circumstances. (How "normal" a diamond is is another matter.)

My comment: There are quantum physics in any temperature.

Sorry, I'm a bit of a nube to this entanglement business. So has entanglement actually been observed between electrons with a large geographical separation or is it just a theory?
