After proving that it is impossible to distill the entanglement of Gaussian states with Gaussian operations, we describe entanglement concentration protocols that involve either cross-Kerr interaction or photon number measurements. If combined with an iterative gaussification procedure, these techniques would allow to implement an entanglement distillation protocol for continuous variables."@en . "Mi\u0161ta, Ladislav" . . .
