Universal entanglement decay in atmospheric turbulence
arXiv:1408.3324 · doi:10.1103/PhysRevA.91.012345
Abstract
We consider the propagation of two photonic qubits, initially maximally entangled in their orbital angular momenta (OAM), across a turbulent atmosphere. By introducing the {\it phase correlation length} of an OAM beam, we show that the entanglement of OAM photons exhibits a universal exponential decay under turbulence.
