Cancellation of atmospheric turbulence effects in entangled two-photon beams

摘要

We introduce a scheme for odd-order aberration-free transmission of two-photon beams through the turbulent atmosphere.We show that a two-photon beam with a Gaussian fourth-order correlation profile can be transmitted through a turbulence cell with very low signal loss. Our scheme relies on the spatial correlations present in two-photon states generated by spontaneous parametric down conversion.
