    "abstract": "A quantum key distribution scheme based on the use of displaced squeezed\nvacuum states is presented. The states are squeezed in one of two field\nquadrature components, and the value of the squeezed component is used to\nencode a character from an alphabet. The uncertainty relation between\nquadrature components prevents an eavesdropper from determining both with\nenough precision to determine the character being sent. Losses degrade the\nperformance of this scheme, but it is possible to use phase-sensitive\namplifiers to boost the signal and partially compensate for their effect.",
