We investigate how entanglement can be transferred between qubits and
continuous variable (CV) systems. We find that one ebit borne in maximally
entangled qubits can be fully transferred to two CV systems which are initially
prepared in pure separable Gaussian field with high excitation. We show that it
is possible, though not straightforward, to retrieve the entanglement back to
qubits from the entangled CV systems. The possibility of deposition of multiple
ebits from qubits to the initially unentangled CV systems is also pointed out.Comment: 4 pages, 3 figures, RevTeX
