“Spooky Action at a Distance”
In 1982, the experiment of A. Alain, J. Delibar, and G. Roger, working at the Optic Institute of the University of Paris, shook the scientific community [1]. For the first time such interaction from very large distances was observed. Two electrons with opposite spin (the spin of the couple was zero) remained connected even when one of the electrons was taken to London and the other to New York. When the spin of one of the electron was changed, the spin of the other electron was automatically changing and the spin of the couple was remaining zero. When the axis of spinning of one of the electrons was tilted at an angle, immediately the second electron was changing its axis of spinning to the same angle when continuing to spin in direction opposite to the spinning of the first. Probably, this is what Einstein called “spooky action at a distance”. In 1935, Einstein wrote the article: “Can Quantum-Mechanical Description of Physical Reality Be Considered Adequate?” [2]. It was a thought experiment to expose the incompleteness of the Quantum Theory, which Einstein disliked from the very beginning.
