Description:
We demonstrate the distribution of quantum entanglement via optical free-space links to independent receivers separated by 600 m, with no line of sight between each other. A Bell inequality between those receivers is violated by more than four standard deviations, confirming the quality of the entanglement. This outdoor experiment represents a step toward satellite-based distributed quantum entanglement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aspelmeyer, Markus -- Bohm, Hannes R -- Gyatso, Tsewang -- Jennewein, Thomas -- Kaltenbaek, Rainer -- Lindenthal, Michael -- Molina-Terriza, Gabriel -- Poppe, Andreas -- Resch, Kevin -- Taraba, Michael -- Ursin, Rupert -- Walther, Philip -- Zeilinger, Anton -- New York, N.Y. -- Science. 2003 Aug 1;301(5633):621-3.
