Quantum communication, our ability to transmission quantum information between remote locations, is a primitive operation necessary for any future quantum internet. At its heart quantum communication relies on establishing entangled links between remote locations which can then be used to teleport quantum data. The ultimate performance of such approaches is limited by photon losses in the optical fiber channels. We introduce the concept of quantum multiplexing, which allows us to both minimize the number of photons needed in the entanglement distribution processing while at the same time enhancing the quality of the entangled pairs generated. Our approach should improve the performance of quantum communication systems and repeater networks.
