    "abstract": "We study the experimental realisation of quantum teleportation as performed\nby Bouwmeester {\\em et al}. [Nature {\\bf 390}, 575 (1997)] and the adjustments\nto it suggested by Braunstein and Kimble [Nature {\\bf 394}, 841 (1998)]. These\nsuggestions include the employment of a detector cascade and a relative\nslow-down of one of the two down-converters. We show that coincidences between\nphoton-pairs from parametric down-conversion automatically probe the\nnon-Poissonian structure of these sources. Furthermore, we find that detector\ncascading is of limited use, and that modifying the relative strengths of the\ndown-conversion efficiencies will increase the time of the experiment to the\norder of weeks. Our analysis therefore points to the benefits of single-photon\ndetectors in non-post-selected type experiments, a technology currently\nrequiring roughly $6^{\\circ}$K operating conditions.",
