    "abstract": "Many quantum computation and communication schemes require, or would\nsignificantly benefit from, true sources of single photon on-demand (SPOD).\nUnfortunately, such sources do not exist. It is becoming increasingly clear\nthat coupling photons out of a SPOD source will be a limiting factor in many\nSPOD implementations. In particular, coupling these source outputs into optical\nfibers (usually single mode fibers) is often the preferred method for handling\nthis light. We investigate the practical limits to this coupling as relates to\nparametric downconversion, an important starting point for many SPOD schemes.\nWe also explored whether it is possible to optimize the engineering of the\ndownconversion sources to improve on this coupling. We present our latest\nresults in this area.",
