Robust entangled qutrit states in atmospheric turbulence — •Tobias Brünner1 and Filippus Stef Roux2 — 1Institute of Physics, Albert-Ludwigs University of Freiburg, Hermann-Herder Str. 3, 79104 Freiburg, Germany — 2CSIR National Laster Centre, P.O. Box 395, Pretoria 0001, South Africa
We consider propagation of entangled photon pairs through atmospheric turbulence, and seek for the entangled qutrit states that are most robust against entanglement decay. Performing optimization of the initial state, we obtain expressions for bipartite qutrit states that retain their initial entanglement longer than the initially maximally entangled states.
