    "abstract": "We show how a qubit can be fault-tolerantly encoded in the\ninfinite-dimensional Hilbert space of an optical mode. The scheme is efficient\nand realizable with present technologies. In fact, it involves two travelling\noptical modes coupled by a cross-Kerr interaction, initially prepared in\ncoherent states, one of which is much more intense than the other. At the exit\nof the Kerr medium, the weak mode is subject to a homodyne measurement and a\nquantum codeword is conditionally generated in the quantum fluctuations of the\nintense mode.",
