Does God Play Dice? And what do physicists play at? Nicolas Gisan, the author of the breakthrough Geneva experiment on the transmission of quantum entanglement of photon pairs over optical fiber, sets out his views on the fundamental questions of quantum physics through the prism of Bell's game - an imaginary experiment that considers the theoretical possibility of superluminal information transmission using entangled particles. Real experiments with them proved the non-local nature of the world - contrary to the intuitive desire of scientists, events at remote points in the Universe can directly depend on each other. The true nature of these phenomena and the ensuing consequences have recently become a hot topic in physics. According to the author, the second quantum revolution, which began in the last decade of the 20th century, will build a new, consistent and fruitful view of the world.
