英文摘要	We propose a method to improve the performance of two entanglement-based continuous-variable quantum key distribution protocols using noiseless linear amplifiers. The two entanglement-based schemes consist of an entanglement distribution protocol with an untrusted source and an entanglement swapping protocol with an untrusted relay. Simulation results show that the noiseless linear amplifiers can improve the performance of these two protocols, in terms of maximal transmission distances, when we consider small amounts of entanglement, as typical in realistic setups.; National Basic Research Program of China (973 Program) [2012CB315605]; National Science Fund for Distinguished Young Scholars of China [61225003]; Fund of State Key Laboratory of Information Photonics and Optical Communications; Engineering and Physical Sciences Research Council (EPSRC); Leverhulme Trust; SCI(E); ARTICLE; yusong@bupt.edu.cn; 7; 4547-4562; 17
