    "abstract": "We introduce new quantum key distribution protocols using quantum continuous\nvariables, that are secure against individual attacks for any transmission of\nthe optical line between Alice and Bob. In particular, it is not required that\nthis transmission is larger than 50 %. Though squeezing or entanglement may be\nhelpful, they are not required, and there is no need for quantum memories or\nentanglement purification. These protocols can thus be implemented using\ncoherent states and homodyne detection, and they may be more efficient than\nusual protocols using quantum discrete variables.",
