We have constructed an entanglement based quantum key distribution system that links three buildings, covering a largest distance of 1575 m. The photons are transmitted via telescopes through free space. In this paper, we give a detailed description of our system and the protocol that we implemented. We analyze system components and design considerations. Some preliminary results of a one-link experiment are presented.
