The Johns Hopkins University, Applied Physics Laboratory, Laurel, MD 20723(Dated: February 9, 2008)We describe the results of a parametric down-conversion experiment in which the detection of onephoton of a pair causes the other photon to be switched into a storage loop. The stored photoncan then be switched out of the loop at a later time chosen by the user, providing a single photonfor potential use in a variety of quantum information processing applications. Although the storedsingle photon is only available at periodic time intervals, those times can be chosen to match thecycle time of a quantum computer by using pulsed down-conversion. The potential use of the storageloop as a photonic quantum memory device is also discussed.I. INTRODUCTION

High efficiency single photon detection via frequency up-conversion (2004, background): “, from a spontaneous parametric down-conversion source[31][32] or a quantum dot source[33][34][35][36]) remains an interesting experimental goal, the immediate application of IR up-conversion at the single-photon level is likely to use attenuated coherent states, the traditional source for fiber qua”
Linear optical quantum computing with photonic qubits (2005, methodology): “Alternatively, we can use the following method of making single-photon sources (Pittman et al. 2002c; Migdall et al. 2002): Consider an array of PDCs with one output mode incident on a photon detector, and the other entering the quantum circuit.”
