Near-term performance of quantum repeaters with imperfect ensemble-based quantum memories
Yu-Feng Wu, Jian-Long Liu, Christoph Simon · Physical Review A · 2020
Four different quantum repeater schemes built with ensemble-based quantum memories are analyzed in order to guide experimentalists to achieve real-world implementations. The work focuses on repeaters devoid of error correction and suggests that meaningful proof-of-principle demonstrations are within reach of current technology.
