    "abstract": "We explore the entanglement of the vacuum of a relativistic field by letting\na pair of causally disconnected probes interact with the field. We find that,\neven when the probes are initially non-entangled, they can wind up to a final\nentangled state. This shows that entanglement persists between disconnected\nregions in the vacuum. However the probe entanglement, unlike correlations,\nvanishes once the regions become sufficiently separated. The relation between\nentropy, correlations and entanglement is discussed.",
