    "abstract": "The safety of a quantum key distribution system relies on the fact that any\neavesdropping attempt on the quantum channel creates errors in the\ntransmission. For a given error rate, the amount of information that may have\nleaked to the eavesdropper depends on both the particular system and the\neavesdropping strategy. In this work, we discuss quantum cryptographic\nprotocols based on the transmission of weak coherent states and present a new\nsystem, based on a symbiosis of two existing ones, and for which the\ninformation available to the eavesdropper is significantly reduced. This system\nis therefore safer than the two previous ones. We also suggest a possible\nexperimental implementation.",
