Quantum Darwinism seen in diamond traps

Summary

How does our predictable everyday world emerge from the nebulous and probabilistic rules of quantum mechanics? This enigma has upset physicists since the emergence of quantum theory in the 1920s to explain the behavior of atoms and other infinitesimal things. Researchers who manipulate an electron trapped in a diamond have confirmed the essential prediction of a theory that attempts to explain this transition from the quantum world to the classical world. Called "quantum Darwinism", the theory holds that classical states are simply the quantum states most likely to survive interactions with their environment to print again and again in their environment. In the experiment, the researchers observed that the electron was printing its quantum state on the nuclei of surrounding atoms, as predicted by the theory. However, physicists warn that the experience is far from being the last word in the matter.
