Abstract

Transmission of entangled state through turbulent atmosphere is studied. The qubits are encoded by modes of the Gaussian beam. The quality of the entanglement transmission is estimated using the distance between the density matrix and the subspace of non-entangled states. It is shown that the values of the distances depend on chosen modes numbers.
