19. It should be noted that precise photon counting would require special detectors such as the ones described in S. Kim, Y. Yamamoto, and H. H. Hogue, Appl. Phys. Lett. APPLAB 0003-6951 10.1063/1.123404 74, 902 (1999). Without such special technology, the effects of photon losses are usually avoided by using down-converted light with r much smaller than one. The effects of higher photon number components can then be neglected even if the detectors have limited quantum efficiencies and cannot resolve photon number. However, this method limits the output intensity and makes it difficult to achieve high photon numbers.
20. A similar robustness of bipartite entanglement against the photon losses caused by limited detector efficiencies has recently been investigated in H. S. Eisenberg, G. Khoury, G. Durkin, C. Simon, and D. Bouwmeester, Phys. Rev. Lett. PRLTAO 0031-9007 10.1103/PhysRevLett.93.193901 93, 193901 (2004). This paper also gives an interesting example of parametric downconversion with r>1.
21. It may be worth noting that the apparent localization of the "wedge" between the quantized measurement results is somewhat similar to the correlation between coherence and half-integer photon number results observable in finite resolution measurements, as discussed in H. F. Hofmann, Phys. Rev. A PLRAAN 1050-2947 10.1103/PhysRevA.61.033815 61, 033815 (2000).
