Physicists Seek Answers to Quantum Correlations

  • When the researchers measured several properties of each photon at its destination, they found that the particles could instantly sense the other´s behavior without any known communication. Although this correlation obeys the laws of quantum mechanics, it seems to defy the nature of space and time, at least from humans´ everyday perspectives.



    The physicists ruled out several possible classical explanations for the instantaneous communication. For one thing, they showed that the photons did not share information before leaving Geneva, and so they didn´t travel knowing about each other´s properties.
