在量子鑰配送的技術面上,有發射源、量子通道、接收端、通訊協定等方面的問題,其中又以通訊協定的演進,對於整個量子鑰配送效能的提升,最能發揮其貢獻。本研究利用Haar小波的基底分析來探討原鑰修正的可行性。Technically, there are some problems at photo sources, quantum channels, detectors, and protocols in quantum key distribution (QKD). Therefore, it has a great part to promote the effect for QKD by improving protocols. We analyze the error-correcting of raw key by using Harr wavelets.
