Chinese physicists break new record in exploiting quantum entanglement

May 12th, 2012 14 comments

Quantum entanglement is a curious physical property of our universe where paired quantum objects, regardless where they are, instantly reflect one another. Albert Einstein called this “Spooky action at a distance.” Photons (light particles) are quantum objects. Physicists have experimentally confirmed this entanglement phenomenon. One way is to split a photon into two lower-energy photons, and the resulting pair becomes entangled. (Here is a good explanation.) Photons have various properties. When a property in the entangled pair is altered, the other’s same property reflects instantaneously. Physicists have demonstrated separating the entangled photons using fiber optics cables. Again, over some distance, the entanglement property holds. Read more…
