主　　题：atmospheric turbulence orbital angular momentum hypergeometric-Gaussian-II beam Holevo channel capacity 

摘      要：We use Hypergeometric Gaussian-II(HyGG-II)modes to investigate the impacts of non-Kolmogorov atmospheric turbulence on the Holevo channel capacity of a quantum communication *** capacity of HyGG-II modes can be higher than that of Laguerre-Gaussian modes via modulating the hollowness *** influences of low-order turbulence aberrations including tilt,defocus,astigmatism,and coma on the capacity are also ***,tilt aberration dominates among all low-order aberrations and defocus and astigmatism aberrations are always *** contrast,the effect of coma aberration can be enhanced to be non-negligible when the turbulence strength or the channel zenith angle is *** also show that only the total and tilt aberrations are sensitive to the non-Kolmogorov power-law *** results may contribute to the quantum optical communication as well as aberration compensation in turbulent channels utilizing the novel family of vortex beams.
