EPR test with photons and kaons: Analogies

We present a unified formalism describing the Einstein-Podolsky-Rosen test using spin 1/2 par-tides, photons, and kaons. This; facilitates the compari son with existing experiments using photons and kaons. It underlines the si milarities between birefringence and polarization-dependent losses that aff ect experiments using optical fibers and mixing and decay that are intrinsi c to the kaons. We also discuss the limitation these two characteristics im pose on the testing of Bell's inequality. (C) 2001 American Association of Physics Teachers.
