量子密钥分发实验中偏振分束器的研究

The research of beam splitter in quantum key distribution

量子密钥分发是量子信息论中发展最快、最接近实用化的领域,偏振分束器是量子密钥分发系统中重要的组成部分,对分束器的经典分析和量子分析得出了完全一致的结果.

The development of the quantum key distribution is the fast and the most practically in quantum information. The beam splitter is one important component of the quantum key distribution. The classical and quantum analysis about beam splitter are accordant.
