  In a recent paper [quant-ph/0607008] Lapaire and Sipe argue that one can
discuss interference experiments using entangled photons in terms of single
photon wave functions. Furthermore, they argue that contrary to the claim of
the authors of the postponed compensation experiment [2], the single photon
wave functions overlap on the beam splitter when interference is observed. In
this comment, we show that the claim in [2] is correct and we argue that the
idea of single photon wave functions in entangled states is misleading.
