Delayed choice quantum eraser experiment in terms of MWI and/or BI

  1. Jan 9, 2009 #1
    I'm sure there's been a lot of posts on this before, but even after taking a look at some of them, this experiment is still eluding my understanding.
    I'm aware that there's no backwards causation--and that the eraser causes interference by random 'categorization'--but I'm nonetheless dissatisfied that I don't have a visual picture of the phenomenon. I know that's it possible to have one through realist interpretations of QM since they (must be) consistent with standard QM equations. Could anyone give me a complete, step-by-step description of the entire standard delayed choice quantum eraser experiment: http://www.bottomlayer.com/bottom/kim-scully/kim-scully-web.htm
    in terms of MWI? or perhaps BI--if not MWI, but I'd prefer MWI--including how the correlation exists in either case? I haven't taken any QM courses (and won't be able to for about a year) so I'd greatly appreciate descriptions that don't stray too far past basic mathematics.
