一种快速且用户友好的量子密钥分发

Fast and User-friendly Quantum Key Distribution

Gregoire Ribordy, Jean-Daniel Gautier, Nicolas Gisin, Olivier Guinnard, Hugo Zbinden

摘要:

提出了比较不同量子密钥分发实验的一些准则。然后介绍了一种改进的“即插即用”干涉系统,允许快速密钥交换。自对准和双折射补偿仍然存在。原始电子执行BB84协议,并允许用户友好的操作。在23 Km安装的电缆上以486 Hz的速率以每脉冲0.1个光子进行密钥创建,其中QBER为5.4%-对应于210 Hz的净速率。

英文摘要:

Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved 'plug & play' interferometric system allowing fast key exchange is then introduced. Self-alignment and compensation of birefringence remain. Original electronics implementing the BB84 protocol and allowing user-friendly operation is presented. Key creation with 0.1 photon per pulse at a rate of 486 Hz with a 5.4% QBER - corresponding to a net rate of 210Hz - over a 23 Km installed cable was performed.
