    "abstract": "Quantum key distribution can be performed with practical signal sources such\nas weak coherent pulses. One example of such a scheme is the Bennett-Brassard\nprotocol that can be implemented via polarization of the signals, or equivalent\nsignals. It turns out that the most powerful tool at the disposition of an\neavesdropper is the photon-number splitting attack. We show that this attack\ncan be extended in the relevant parameter regime such as to preserve the\nPoissonian photon number distribution of the combination of the signal source\nand the lossy channel.",
