    "abstract": "The first optical proposal for the realization of the two-bit version of the\nDeutsch-Jozsa algorithm [D. Deutsch and R. Jozsa, Proc. R. Soc. London A {\\bf\n493}, 553 (1992)] is presented. The proposal uses Stark shifts in an ensemble\nof atoms and degenerate sources of photons. The photons interact dispersively\nwith an atomic ensemble, leading to an effective Hamiltonian in atom-field\nbasis, which is useful for performing the required two-qubit operations.\nCombining these with a set of one-qubit operations, the algorithm can be\nimplemented. A discussion of the experimental feasibility of the proposal is\ngiven.",
