6. To be exact, the state of light generated via SPDC is given by a superposition of vacuum and two-photon states. However, in many experiments, including the one discussed here, the vacuum state makes no contribution.

14. Another way to avoid equalizing optical path lengths is to join radiation from different crystals in the far-field zone, instead of using a beam splitter; see A. V. Burlakov et al, Phys. Rev. A 56, 3214 (1997).
