The past decade has seen tremendous progress in experimentally realizing the building blocks of quantum repeaters. Repeater architectures with multiplexed quantum memories have been proposed to increase entanglement distribution rates, but an open challenge is to maintain entanglement fidelity over long distances. In this thesis, I present a quantum router architecture comprising many quantum memories connected in a photonic switchboard to broker entanglement flows across quantum networks. The quantum router achieves channel-loss-invariant fidelity and automatically prioritizes entanglement flows across repeater chains without requiring global network information. I further propose algorithms for local entanglement routing across general networks of multiplexed repeaters to optimize entanglement rates and fidelities.
