混合并行量子密钥分发协议

Hybrid Parallel Quantum Key Distribution Protocol

Fabio Alencar Mendonca, Rubens Viana Ramos

摘要:

使用单光子或弱相干态的BB84量子密钥分发协议的实际实现通常表现出低效率,这意味着Alice发送的大多数比特对于最终密钥没有用处。在这项工作中,我们提出了一种光学设置,以提高传输率的有用比特结合两个想法,并行量子密钥分发和物理加密使用介观相干态。最终的结果是四倍更快的量子密钥分发设置。

英文摘要:

The practical realizations of BB84 quantum key distribution protocol using single-photon or weak coherent states have normally presented low efficiency, in the meaning that most bits sent by Alice are not useful for the final key. In this work, we show an optical setup to improve the transmission rate of useful bits putting together two ideas, parallel quantum key distribution and physical encryption using mesoscopic coherent states. The final result is a four time faster quantum key distribution setup.
