摘要：

We show that the security proof of the Bennett 1992 protocol over loss-free channel given by Tamaki, Koashi, and Imoto [Phys. Rev. Lett. 90, 167904 (2003)] can be adapted to accommodate loss. We assumed that Bob's detectors discriminate between single-photon states on one hand and vacuum state or multiphoton states on the other hand.
