基于不同介质间量子密钥分发的研究
Study on quantum key distribution b etween different media
摘要
Abstract
This paper mainly solves the photon polarization encoding problem of quantum key distribution (QKD) between different media. The influence of the transmission rate of different photon component on quantum bit error rate (QBER) has been quantitatively analyzed, with a practical analysis of QBER of QKD between air and water. Furthermore, we have put forward a single-photon compensation scheme for eliminating such non-ideal BB84 protocol, as well as a more robust and practical dual-photon encoding scheme to offset such interfacial non-unitary noise. This takes an important step towards the air-sea-ground wide area quantum communication in the future.关键词
