Chang, Ping; Shao, Bin; Long, Gui Lu Entanglement transfer from photon-subtracted and photon-added two-mode squeezed fields to a pair of qubits. (English) Zbl 1227.81069 Phys. Lett., A 372, No. 48, 7124-7128 (2008). Summary: We investigate the entanglement transfer from a bipartite non-Gaussian continuous-variable (CV) system to a pair of localized qubits. The non-Gaussian state is obtained by the de-Gaussification process involving subtracting photons from or adding photons to a Gaussian field. It is shown that such de-Gaussification process can improve the entanglement transfer.
