This paper presents a continuous variable, second generation, quantum repeater scheme for entanglement distribution over a lossy bosonic channel that beats the direct transmission exponential rate-loss tradeoff. The scheme is primarily based on noiseless linear amplification with the quantum scissors and a layer of switched, mode multiplexing

Using the quantum scissors operation for entanglement distillation and a single-rail Bell state projection for non-Gaussian entanglement swapping, we show a multiplexed quantum repeater scheme for continuous-variable entanglement distribution over a pure loss communication channel.
