Eavesdropping on the "ping-pong" quantum communication protocol
arXiv:quant-ph/0211199 · doi:10.1103/PhysRevLett.90.157901
Abstract
The proposed eavesdropping scheme reveals that the quantum communication protocol recently presented by Bostrom and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)] is not secure as far as quantum channel losses are taken into account.
