Physicists Create Quantum Twin Atoms (http://www.sciencedaily.com/releases/2011/05/110501183605.htm)
QuoteScienceDaily (May 2, 2011) — Objects that are well separated in space but still cannot be understood separately belong to the profoundest mysteries of quantum physics. Pairs of photons are prominent examples of such systems. They allow the teleportation of quantum states or tap-proof data transfer using quantum cryptography. In future, such experiments will not be restricted simply to photons. At the Vienna University of Technology (TU Vienna), a method has been developed to create correlated pairs of atoms using ultracold Bose-Einstein condensates.
This goes over my head but it makes interesting reading for the masochistically inclined! ;D
