I Delayed choice quantum eraser

  1. Mar 5, 2016 #1
    Hi, I have a simple question regarding this experiment:

    If we were to place a new detector, say D5, immediately after BSa, would it mean that D0 never shows an interference pattern for D5? I think so, as it would seem this should be no different than the result obtained at D3, but just want to confirm my understanding of the experiment (and try to convince myself that that the light traveling through or interacting with intermediate materials (e.g. beam splitters, mirrors, etc.) is not materially affecting the results).
