Quantum non-locality in ultra-cold atomic gases
(PHYSorg.com Physics)

Non-locality, Einstein`s ``spooky action at a distance,` has been observed between quantum objects separated by more than one kilometer. Recent years have seen a major advancement in the quest for non-local systems. Researchers from the Faculty of Physics, University of Warsaw, present a novel and versatile method for creating and detecting such correlations in a many-body system of ultra-cold atoms. They have published their results in Physical Review Letters.
