A 66, 042303 (2002), https://doi.org/10.1103/PhysRevA.66.042303https://doi.org/10.1103/PhysRevA.66.042303http://hdl.handle.net/11603/19291We describe the results of a parametric down-conversion experiment in which the detection of one photon of a pair causes the other photon to be switched into a storage loop. The stored photon can then be switched out of the loop at a later time chosen by the user, providing a single photon for potential use in a variety of quantum information processing applications. Although the stored single photon is only available at periodic time intervals, those times can be chosen to match the cycle time of a quantum computer by using pulsed down-conversion. The potential use of the storage loop as a photonic quantum memory device is also discussed.7 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
