Entanglementis an essential quantum resource for the acceleration of informationprocessing as well as for sophisticated quantum communication protocols. Quantuminformation networks are expected to convey information from one placeto another by using entangled light beams. We demonstrated thegeneration of entanglement among three bright beams of light, allof different wavelengths (532.251, 1062.102, and 1066.915 nanometers). We alsoobserved disentanglement for finite channel losses, the continuous variable counterpartto entanglement sudden death. ©2009 American Association for the Advancement of Science
