Finite-range multiplexing in tripartite quantum networks — •Julia Alina Kunzelmann, Hermann Kampermann, and Dagmar Bruß — Institut für Theoretische Physik III, Heinrich-Heine-Universität Düsseldorf
Due to the interaction between qubits and their environment, long-distance communication still poses a challenge. To overcome this problem, quantum repeaters are used, in which the repeater rate can be maximized by utilizing multiplexing. In previous work (Abruzzo et al. (2014)), a finite-range multiplexing protocol for two parties was investigated. We extend this protocol to three parties and it turns out that also in the tripartite network, full-range multiplexing does not provide substantial advantages over finite-range multiplexing. We also analyze decoherence of quantum memories and various strategies to lower the experimental requirements. To achieve this, different three-dimensional matching strategies are analyzed.
