    "abstract": "We investigate spatial entanglement - particle-number entanglement between\nregions of space - in an ideal Bosonic gas. We quantify the amount spatial\nentanglement around the transition temperature for condensation by probing the\ngas with two localised two-level systems. We show that spatial entanglement in\nthe gas is directly related to filling of the ground state energy level and\ntherefore to the off-diagonal long-range order of the system and the onset of\ncondensation.",
