説明

Summary: We propose a simple quantum cryptographic scheme involving truly two orthogonal states. The security of the protocol is based on splitting the transfer of one-bit information into two steps, ensuring that only a fraction of the bit information is transmitted at a time. A particular implementation with an asymmetric interferometer is presented, which does not require the random timing of the packet sending as was used by \textit{L. Goldenberg} and \textit{L. Vaidman} [Phys. Rev. Lett. 75, No. 7, 1239-1243 (1995)].
