I have a misunderstanding about the beam splitter in this experiment
High fidelity entanglement swapping with fully independent sources
Rainer Kaltenbaek, Robert Prevedel, Markus Aspelmeyer,Anton Zeilinger
http://arxiv.org/pdf/0809.3991.pdf
Part of the diagram is reproduced here
Two photons ( 2 and 3 ) arrive at BS and coincidences between the four counters ##D_{Q1H}## to ##D_{Q2V}## are detected.
The authors say "A two-fold coincidence detection event between either DQ1H and DQ2V or DQ1V and DQ2H indicates ...". But this requires that one photon should be present in each output beam. I don't see how this can happen if they are expecting HOM interference.
What am I missing ?
