    "abstract": "We suggest a quantum cryptographic scheme using continuous EPR-like\ncorrelations of bright optical beams. For binary key encoding, the continuous\ninformation is discretized in a novel way by associating a respective\nmeasurement, amplitude or phase, with a bit value \"1\" or \"0\". The secure key\ndistribution is guaranteed by the quantum correlations. No pre-determined\ninformation is sent through the quantum channel contributing to the security of\nthe system.",
