    "abstract": "We prove the unconditional security of the original Bennett 1992 protocol\nwith strong reference pulse. We show that we may place a projection onto\nsuitably defined qubit spaces before the receiver, which makes the analysis as\nsimple as qubit-based protocols. Unlike the single-photon-based qubits, the\nqubits identified in this scheme are almost surely detected by the receiver\neven after a lossy channel. This leads to the key generation rate that is\nproportional to the channel transmission rate for proper choices of\nexperimental parameters.",
