Quantum entanglement of two particles means that if something happens to one particle, it affects the other, no matter how far away it is. The phenomenon seems to break some of the bedrock rules of standard physics: that nothing can travel faster than light, that objects are only influenced by their immediate surroundings. And scientists still can't explain how entangled particles are linked. Albert Einstein derisively called the concept "spooky action at a distance."
In a new study, scientists report that they were able to produce entangled photons on a satellite orbiting 300 miles above the planet and beam the particles to two different ground-based labs that were 750 miles apart, all without losing the particles' strange linkage. It is the first time anyone has ever generated entangled particles in space, and represents a 10-fold increase in the distance over which entanglement has been maintained.
