Secure optical communications using antisqueezed light with enhanced fluctuations
Tatsuya Tomaru, Shinya Sasaki · Conference on Lasers and Electro-Optics · 2008
Secure optical communications using antisqueezing are a realistic application of quantum information technologies. Antisqueezed light with enhanced fluctuations was transmitted over 100 km. Greater difficulty of eavesdropping than in a coherent-state case was shown.
