- Sorry, I don't follow your objection. This wave function isn't
- dependent on the relative angle, explicitly or otherwise. I can expand
- the polarization kets in any basis I choose. I choose to expand each
- ket in a basis aligned with the polarizer the "attached" wavefront
- encounters. This is to separate out the term that gets absorbed from
- the one that goes through. The relative angle comes from applying that
- expansion separately to the kets attached to distant wavefronts.
-
- The wave function itself is unaffected by changing the transmission
- angle of a polarizer, except that it affects the component absorbed
- when a wavefront encounters it -- exactly as in the one-photon case.
