    "abstract": "We demonstrate theoretically and experimentally that secure communication\nusing intermediate-energy (mesoscopic) coherent states is possible. Our scheme\nis different from previous quantum cryptographic schemes in that a short secret\nkey is explicitly used and in which quantum noise hides both the bit and the\nkey. This encryption scheme can be optically amplified. New avenues are open to\nsecure communications at high speeds in fiber-optic or free-space channels.",
