    "abstract": "A continuous key distribution scheme is proposed that relies on a pair of\ncanonically conjugate quantum variables. It allows two remote parties to share\na secret Gaussian key by encoding it into one of the two quadrature components\nof a single-mode electromagnetic field. The resulting quantum cryptographic\ninformation vs disturbance tradeoff is investigated for an individual attack\nbased on the optimal continuous cloning machine. It is shown that the\ninformation gained by the eavesdropper then simply equals the information lost\nby the receiver.",
