摘要:

在单光子不完全产生和检测的假设下,研究了一个确定性量子通信方案LM05 [1]在有耗信道中的安全性.结果表明,该方案允许可加密安全比特的速率高于BB84 [2]。我们报告的第一个实施LM05与弱脉冲。

英文摘要:

The security of a deterministic quantum scheme for communication, namely the LM05 [1], is studied in presence of a lossy channel under the assumption of imperfect generation and detection of single photons. It is shown that the scheme allows for a rate of distillable secure bits higher than that pertaining to BB84 [2]. We report on a first implementation of LM05 with weak pulses.
