High-speed modulation of quantum state by optical soliton

ZHAO Yi-hong,LI Zheng-wen,LIU Yong-zhi,HE Qi-si (Information Engineering College of Chengdu University of Technology, Chengdu 610059,China)  
A modulation method of a quantum communication system is studied and a scheme of modulating quantum states in high-speed with soliton is proposed in the paper. The transmission evolution of soliton in NLSE optic fiber and in SIT media is demonstrated by modulating communication channel of quantum state, respectively. It is concluded that two-component transmission line can produce quantum entangled states (or squeezed states) in the soliton transmission.The wavicle of light is used for the modulation and the properties of quantum and soliton are fused. This scheme is a development trend for future quantum communication.
