17. When dead times are significant [see, for example, H.-A. Bachor, A Guide to Experiments in Quantum Optics (Wiley, Brisbane, 1998), p. 144] more sophisticated detection methods are required. Most photodetectors can only discriminate between no photons and some photons or, more recently, between zero, one, and more than one photons in an interval shorter than the dead time. One approach to overcoming this difficulty involves replacing each detector by a number of photodetectors in the outputs of a suitable multiport device;
