The evolution of an entangled photon state propagating through a turbulent\natmosphere is formulated in terms of a set of coupled first order differential\nequations, by using an infinitesimal propagation approach. The orbital angular\nmomentum (OAM) basis is used to described the density matrix of the state.\nAlthough the analysis is done in the paraxial limit for a monochromatic optical\nfield, the formalism is comprehensive in the sense that it does not require any\nassumptions about the strength of the turbulence and it can incorporate any\nspectral model for the turbulence. As a comparative example the case of\nentangled qubit OAM biphoton states is considered.\n
