Shor-Preskill Type Security-Proof for the Quantum Key Distribution without Public Announcement of Bases
W. -Y. Hwang, X. -B. Wang, K. Matsumoto +2
We give a Shor-Preskill type security-proof to the quantum key distribution without public announcement of bases [W.Y. Hwang et al., Phys. Lett. A 244, 489 (1998)]. First, we modif…

Shor-Preskill Type Security-Proofs for Concatenated Bennett-Brassard 1984 Quantum Key Distribution Protocol
W. -Y. Hwang, K. Matsumoto, H. Imai +2
We discuss long code problems in the Bennett-Brassard 1984 (BB84) quantum key distribution protocol and describe how they can be overcome by concatenation of the protocol. Observin…
