• Abstract summary: We study fluctuations of light beams propagating through a turbulent atmosphere. The size of the quasiclassical part of wandering decreases with the propagation distance, while the quantum part increases. The effect of the phase diffuser on the fourth moment (FM) of the irradiance is taken into account.

• Abstract: The method of photon distribution function (PDF) is used to study fluctuations of light beams propagating through a turbulent atmosphere. Our analysis concerns the regime of saturated fluctuations. The focus is on the phenomena of beam wandering and the effect of partial coherence on photon density fluctuations. It is shown that the size of the quasiclassical part of wandering decreases with the propagation distance, while the quantum part increases. We explain this qualitative difference by beam fragmentation, which is accompanied by a loss of correlation between individual parts. The effect of the phase diffuser on the fourth moment (FM) of the irradiance is taken into account. The obtained explicit expression for the FM indicates the possibility of a significant reduction of noise in the communication channel. The diffuser changes the shot noise from delta-correlated (in the spatial domain) to smoothly distributed. The theory developed here is used to estimate the influence of the phase diffuser on light fluctuations.

  spectrally narrow, spin-dependent optical transitions of nitrogen vacancy center defects in diamond can be harnessed for quantum networking applications. Key to such networking schemes is the generation of indistinguishable photons. Two challenges limit scalability in such systems: defect-to-defect variations of the optical transition caused by local strain variation, and spectral diffusion of the optical frequencies on repeated measurement caused by photoexcitation of nearby charge traps.
