Franson, J. D.; Donegan, M. M.; Fitch, M. J.; Jacobs, B. C.; Pittman, T. B. Experimental progress in linear optics quantum computing. (English) Zbl 1152.81713 Quantum Inf. Comput. 3, Suppl., 553-562 (2003). Summary: Probabilistic quantum logic operations can be performed using linear optical elements and post-selection based on the results of measurements on ancilla photons. We review the results of a number of recent experiments in this area, including the demonstration of several quantum logic gates, the use of feed-forward control, a new source of single photons, and a quantum memory device for single photons. A high-fidelity approach in which the logic gates always produce an output will also be discussed. MSC: 81P68 Quantum computation PDFBibTeX XMLCite \textit{J. D. Franson} et al., Quantum Inf.
