• Resumen

  • As weird as the quantum world is, something happened in 2013 in the shadow of the French Alps that caused even hardened quantum physicists to do a double take. At the Institut Laue-Langevin in Grenoble France, where a nuclear reactor spews out the world's most intense beam of neutrons, physicists made these particles perform a trick that until now had only existed in the fevered imaginations of theorists. In doing so, they have upset our notion of reality. The international team of physicists coaxed the neutrons to shed their quantum properties, getting the particles to go one way and their spins another way. It's as if one took one path and his personality another. Theorists have predicted the possibility of such strange behavior for more than a decade. Here, Ananthaswamy reports how an experiment which shows that quantum particles can lose identity d redefining reality.
