    "abstract": "The efficient experimental verification of entanglement requires an\nidentification of the essential physical properties that distinguish entangled\nstates from non-entangled states. Since the most characteristic feature of\nentanglement is the extreme precision of correlations between spatially\nseparated systems, we propose a quantitative criterion based on local\nuncertainty relations (quant-ph/0212090). Some basic sum uncertainty relations\nfor N-level systems are introduced and the amount of entanglement that can be\nverified by violations of the corresponding local uncertainty limit is\ndiscussed.",
