Closer To Quantum Computing 

Scientists have demonstrated the transfer of physical properties between two entangled atoms through the odd phenomena of quantum teleportation.
Teleportation between atoms could someday lie at the heart of powerful quantum computers, which are probably at least a decade away from development, [David J.] Wineland said. Although his work moved information about atomic characteristics only a tiny fraction of an inch, that's in the ballpark for what would be needed inside a computer, he said.

Key to the process was a phenomenon called entanglement, which Einstein derided as "spooky action at a distance" before experiments showed it was real.

Basically, researchers can use lab techniques to create a weird relationship between pairs of tiny particles. After that, the fate of one particle instantly affects the other; if one particle is made to take on a certain set of properties, the other immediately takes on identical or opposite properties, no matter how far away it is and without any apparent physical connection to the first particle.
