    "abstract": "We propose and study a method for detecting ground-state entanglement in a\nchain of trapped ions, which realizes a suggested scheme for detecting vacuum\nentanglement in quantum field theory. We show that the entanglement between\nsingle ions or groups of ions can be swapped to the internal levels of two ions\nby sending laser pulses that couple the internal and motional degrees of\nfreedom. This allows to entangle two ions without actually doing gates. A proof\nof principle of the effect can be realized with two trapped ions and is\nfeasible with current technology.",
