Long-Distance Entanglement Distribution with Single-Photon Sources
arXiv:0706.1924 · doi:10.1103/PhysRevA.76.050301
Abstract
We present an efficient architecture for quantum repeaters based on single-photon sources in combination with quantum memories for photons. Errors inherent to previous repeater protocols using photon-pair sources are eliminated, leading to a significant gain in efficiency. We establish the requirements on the single-photon sources and on the photon detectors.
