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
