Abstract:
This paper presents a comprehensive analysis on capacity of free space optics (FSO) for classical and quantum communications, since FSO is one of enabler technologies for the sixth generation (6G) of telecommunication, of which the understanding on the differences between classical and quantum channel capacity becomes critical to support the future development. The classical channel models, assuming the effects of atmospheric turbulence in the irradiance distribution, is analyzed both computationally and analytically through closed-form expressions. On the other hands, quantum channel models are analyzed by taking into account the probability of errors caused by turbulence. This paper reveals that the turbulence significantly degrades the capacity of the classical channel compared to the quantum channel; however the degrades in quantum channel is less extreme. Remarkably, none of the quantum channel models experience a drastic drop to zero capacity, where 4 out of 6 models are consistently maintaining non-zero capacity performances.
