Je cite un papier:
http://arxiv.org/PS_cache/quant-ph/p.../0508202v1.pdfEven though, in principle, all particles can be treated as field excitations,
photons are much different from massive particles. They are also different from
massless neutrinos since the photon number does not obey a conservation law.
There are problems with the photon localization and as a result the position
operator for the photon is ill-defined, but the similarities between photons and
other quantum particles are so ample that the introduction of the photon wave
function seems to be fully justified and even necessary in order to achieve a
complete unification of our description of all particles.
C'est quelque chose d'assez bien connu, qui me parait contraire à :
