Query: Noiseless Linear Amplifiers in Entanglement-Based Continuous-Variable
  Quantum Key Distribution   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.
