  There have recently been interests in transferring entanglement between two
quantum systems in different Hilbert spaces. In particular, the study of
entanglement transfer from a continuous-variable to a qubit system has a
primary importance due to practical implications. A continuous-variable system
easily propagates entanglement while a qubit system is easy to manipulate. We
investigate conditions to entangle two two-level atoms for a broad-band
two-mode squeezed field driving the cavities where the atoms are.
