Description:
Author(s): Heng Zhang, Jian Fang, and Guangqiang He We propose a method to improve the secret key rates of four-state continuous-variable quantum key distribution by using an optical preamplifier. The modified protocol allows the distribution of higher secret key rates over long distances. Included in this paper is a detailed investigation of the eff... [Phys. Rev.
