    "abstract": "We study the accumulation of entanglement in a memory device built out of two\ncontinuous variable (CV) systems. We address the case of a qubit mediating an\nindirect joint interaction between the CV systems. We show that, in striking\ncontrast with respect to registers built out of bidimensional Hilbert spaces,\nentanglement superior to a single ebit can be efficiently accumulated in the\nmemory, even though no entangled resource is used. We study the protocol in an\nimmediately implementable setup, assessing the effects of the main\nimperfections.",
