Hello,
I am trying to perform the DIY quantum eraser experiment, but I'm having some trouble. When I perform the classic double slit experiment using a cheap laser pointer and a piece of wire I get a beautiful interference pattern as expected. However when I try the DIY QE experiment I still get an interference pattern, but slightly smudged. I'm using cheap cardboard 3D glasses for the polarizers. I lined up perpendicular pieces and cut them straight. I butted them up against each other and covered the joint with a piece of wire. I've double checked the alignment of the polarizers several times, but I'm still getting the interference pattern. Could my laser pointer be too low quality? Are the polarizing lenses ineffective? Or do I misunderstand the experiment? Any help would be appreciated.
Thanks.
