Abstract
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.
