The phenomenon of quantum entanglement is a situation in which information between two subatomic particles is transferred in a manner that seems to be instantaneous (faster than the speed of light). Einstein referred to it as "spooky action at a distance". Scientists from the Institute for Quantum Computing (IQC) at the University of Waterloo are saying they have demonstrated for the first time that three subatomic particles can be entangled.
Although interesting I don't consider this to be the most significant aspect of their work. What I consider to be the most significant aspect of their work is that it reinforces the results of many other quantum entanglement experiments that indicate faster than light travel of information (though not of matter) on the quantum level is possible. (The implication is that at least something can travel faster than light.) Of tremendous interest to me is that the question of how the information is transferred remains unanswered.
The articles below elaborate. The first is about the nature of quantum entanglement. The next two are about an experiment done only a year ago (March 2013) on whether quantum entanglement indicates faster than light travel. It was done by a team of researchers led by Professor Juan Yin at the University of Science and Technology of China in Shanghai. The results supposedly indicate that quantum entanglement involves travel of information on the quantum level at a speed of at least 10,000 times that of light. The last is about the recent demonstration that three subatomic particles can be entangled.
