    "abstract": "Quantum information processing using photons has recently been stimulated by\nthe suggestion to use linear optics, single photon sources and detectors. The\nrecent work by Knill has also shown that errors in photon detectors leads to a\nhigh error rate threshold (around 29%). An important missing element are good\nsingle photon sources. In this paper we show how to make a single photon source\nusing squeezed states, linear optics and conditional measurement. We use\ndegenerate squeezed vacuum states, in contrast to the normal non-degenerate\nsqueezed vacuum states used for single photon production. We show that we can\nget a photon with certainty when detectors click appropriately, the last event\nhappening up to around 25% of the time. We also show the robustness of this\nmethod with respect to a variety of potential imperfections.",
