+ - Physicists Measure Einstein's "Spooky Action at a Distance"

Hugh Pickens writes writes: "Sebastian Anthony reports that a team of Chinese physicists have clocked the speed of spooky action at a distance — the seemingly instantaneous interaction between entangled quantum particles — at more than four orders of magnitude faster than light (PDF) — around 3 trillion meters per second. Spooky action at a distance is the term coined by Einstein to describe how entangled quantum particles seem to interact with each other instantaneously, over any distance, breaking the speed of light and thus relativity. "As of our current understanding of quantum mechanics, though, it is impossible to send data using quantum entanglement, preserving the theory of relativity," writes Anthony adding that "a lot of work is being done in this area, though, and some physicists believe that faster-than-light communication might be possible with some clever manipulation of entangled particles.""
