The reach of the spooky quantum link called entanglement keeps getting longer. A team has transmitted entangled photons some 144 kilometers (89 miles) between La Palma and Tenerife, two of Spain's Canary Islands off the coast of Morocco. Physicist Anton Zeilinger of the University of Vienna, the group's leader, presented the results to his colleagues this week at the American Physical Society conference.
The distance achieved is 10 times farther than entangled photons have ever flown through the air. When two photons or other particles are in this state, what happens to one determines the fate of the other, no matter how far apart they are. Zeilinger compares the phenomenon with throwing a pair of dice that land on matching numbers every time.

Can't you potentially use entangled photons to instantly communicate information? or does the entanglement breakdown once you access any information and then you are left with no way to communicate?
