The optical signal transmitted on a fiber with thermal noise, attenuation and amplification is studied. The channel is considered as a quantum channel while the signal to be transmitted is classical. The classical information is encoded in a quantum state then it is transmitted in optical fiber. At the receiving end, measurement is performed on the output quantum state to retrieve the classical information...
The optical signal transmitted on a fiber with phase damping is studied. At the limitation of complete damping, we prove that the channel is in fact a classical channel. The complete phase damping channel maps the coherent state to a Poisson distributed state. Classical information is encoded in the parameter of the coherent state, the general input is a probability distribution of coherent states...
