    "abstract": "It is shown how the quantumness of atom-atom correlations in a trapped\nbosonic gas can be made observable. Application of continuous feedback control\nof the center of mass of the atomic cloud is shown to generate oscillations of\nthe spatial extension of the cloud, whose amplitude can be directly used as a\ncharacterization of atom-atom correlations. Feedback parameters can be chosen\nsuch that the violation of a Schwarz inequality for atom-atom correlations can\nbe tested at noise levels much higher than the standard quantum limit.",
