SUMMARY
The discussion centers on the behavior of a polarizing beam splitter (PBS) when horizontal and vertical polarized lenses are pasted over its respective outlets. It concludes that the addition of these lenses does not alter the behavior of the PBS, particularly in an interferometer setup where two PBSs are used back to back. When a |45°⟩ photon is directed into PBS(0°) with pasted lenses, the output remains |45°⟩ when measured at PBS(45°). However, a non-reviewed paper by David Ellerman claims that interference is lost with the modified PBS, a claim that is met with skepticism by participants in the discussion.
