Experimental Observation of Environment-induced Sudden Death of Entanglement
arXiv:quant-ph/0701184 · doi:10.1117/12.724472
Abstract
We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we show that, while the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear. This "sudden death" constitutes yet another distinct and counter-intuitive trait of entanglement.
