(Dated: June 14, 2013)We generalize measurement-device-independent quantum key distribution [ H.-K. Lo, M. Curty,and B. Qi, Phys. Rev. Lett. 108, 130503 (2012) ] to the scenario where the Bell-state measurementstation contains also heralded quantum memories. We find analytical formulas, in terms of deviceimperfections, for all quantities entering in the secret key rates, i.e., the quantum bit error rateand the repeater rate. We assume either single-photon sources or weak coherent pulse sources… CONTINUE READING
