论文摘要
量子中继器对于量子网络的发展至关重要，这使纠缠分布的速率超出了直接传输可实现的速率。我们考虑通过涉及无噪声线性扩增和双重同源检测的中继器，考虑多个连续变化的，挤压的基于光的纠缠流。通过分析中继器中具有不对称损失的单重仪增强通道模型，我们确定了中央中继器中心集线器在4用户轮毂和辐条网络中的最佳位置，以使每个通过轮毂的纠缠流的速率增强。
Quantum repeaters are critical to the development of quantum networks, enabling rates of entanglement distribution beyond those attainable by direct transmission. We consider multiple continuous-variable, squeezed light-based entanglement flows through a repeater involving noiseless linear amplification and dual homodyne detection. By analyzing a single-repeater-enhanced channel model with asymmetric losses across the repeater, we determine optimal placements of the central repeater hub in a 4-user hub-and-spoke network such that the rate of each entanglement flow through the hub is enhanced.
