Entanglement transfer from photon-subtracted and photon-added two-mode squeezed fields to a pair of qubits

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.
