    "abstract": "We demonstrate the difference between local, single-particle dynamics and\nglobal dynamics of entangled quantum systems coupled to independent\nenvironments. Using an all-optical experimental setup, we show that, while the\nenvironment-induced decay of each system is asymptotic, quantum entanglement\nmay suddenly disappear. This \"sudden death\" constitutes yet another distinct\nand counter-intuitive trait of entanglement.",
