摘要：
New methods in optical communications rely on the quantum properties of photons to assure link security and data privacy. However, optical quantum communications make several assumptions, among them that the quantum properties of photons are preserved over many-kilometer long continuous fiber, which additionally is free from absorbing and scattering centers. In this paper we review quantum communication methods based on photon polarization, single and entangled, and we investigate the impact of noise sources on quantum signal propagation.
