DOI: 10.1038/s41566-017-0010-6
Abstract: Quantum repeaters1–4 are essential elements for demonstrating global-scale quantum communication. Over the past few decades, tremendous efforts have been dedicated to implementing a practical quantum repeater5–10. However, nested purification1, the backbone of a quantum repeater,… read more here.

DOI: 10.1103/physreva.103.032610
Abstract: The rate at which quantum communication tasks can be performed using direct transmission is fundamentally hindered by the channel loss. Quantum repeaters allow one, in principle, to overcome these limitations, but their introduction necessarily adds… read more here.

DOI: 10.1103/physreva.99.032349
Abstract: We present a "hybrid quantum repeater" protocol for the long-distance distribution of atomic entangled states beyond qubits. In our scheme, imperfect noisy entangled pairs of two qudits, i.e., two discrete-variable $d$-level systems, each of, in… read more here.

DOI: 10.1103/physrevlett.130.213601
Abstract: A quantum repeater node is presented based on trapped ions that act as single photon emitters, quantum memories and an elementary quantum processor. The node's ability to establish entanglement across two 25 km-long optical fibers… read more here.
