    "abstract": "The practical realizations of BB84 quantum key distribution protocol using\nsingle-photon or weak coherent states have normally presented low efficiency,\nin the meaning that most bits sent by Alice are not useful for the final key.\nIn this work, we show an optical setup to improve the transmission rate of\nuseful bits putting together two ideas, parallel quantum key distribution and\nphysical encryption using mesoscopic coherent states. The final result is a\nfour time faster quantum key distribution setup.",
