    "abstract": "We examine several proposed schemes by Franson et al. for quantum logic gates\nbased on non-local exchange interactions between two photons in a medium. In\nthese schemes the presence of a {\\em single} photon in a given mode is supposed\nto induce a large phase shift on another photon propagating in the same medium.\nWe conclude that the schemes proposed so far are not able to produce the\nrequired conditional phase shift, even though the proposals contain many\nstimulating and intriguing ideas.",
