We present recent work of our group in the field of long distance quantum communication. First, we present a feasibility experiment of a simple e-way scheme which is robust to photon number splitting attacks. Then, we show results on a rapid upconversion photon detector, which could increase the maximum rates of quantum key distribution (QKD). Finally, we present a teleportation experiment over a commercial fiber network. This would be an ingredient of a future quantum relay, which could increase the reach of QKD
