Abstract:Objective In the space channel continuous variable quantum key distribution (CVQKD), the quantum coherent state modulation system is more versatile with the classical optical communication equipment, and has better compatibility with the fiber channel. It is one of the future space channel CVQKD network construction schemes. Aiming at the effects of beam expansion, absorption, scattering, and drift of optical quantum signals in turbulent channels, as well as the phase difference jitter between local oscillator… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
