Abstract
A 1.1km long all-fiber quantum key distribution experimental setup has been realized for the first time at 850nm. The system employs the BB84 protocol to establish a secret key between two parties, the security of which is gu aranteed by Heisenberg's uncertainty relationship and the quantum nonclonin g principle. Phase modulated single photons are used to carry the key. The effective transmission rate is 3 bit/s, with a bit error rate of 9%.
