I have a question regarding Kim et al DCQE experiment: http://arxiv.org/pdf/quant-ph/9903047v1 (also found at wikipedia.org). I have seen a number of (very) different schematics of the experiment. The best one reviewed by Dr. Kim is at: bottomlayer.com/bottom/kim-scully/kim-scully-web.htm However, I still do not get the Glan Thompson Prism (Prisms? I have seen both one or two in schematics). In the original paper the authors say, "A Glen-Thompson prism is used to split the orthogonally polarized signal and idler." Is this to say that all the "signal" photons are of the same polarization as are all the "idler" That is to say, are all the photons in the signal path "p" polarization, and all the idler path "s" polarization?
P.S. Is there a photo of the original experiment anywhere?
