    "abstract": "We calculate eavesdropper\u0027s optimal information on raw bits in\nBennett-Brassard 1984 quantum key distribution (BB84 QKD) and six-state scheme\nin coherent attacks, using a formula by Lo and Chau [Science 283 (1999) 2050]\nwith single photon assumption. We find that eavesdropper\u0027s optimal information\nin QKD without public announcement of bases [Phys. Lett. A 244 (1998) 489] is\nthe same as that of a corresponding QKD WITH it in the coherent attack. We\nobserve a sum-rule concerning each party\u0027s information.",
