Possible evidence for Quantum Darwinism found in quantum dots

Quantum Darwinism is a theory explaining the emergence of the classical world from the quantum world as a process of Darwinian natural selection; where the many possible quantum states are selected against in favor of a stable pointer state.

A new study provides possible preliminary support for this theory.

"[A] team of physicists and engineers from Arizona State University and the Naval Research Laboratory in Washington, D.C., has performed experiments using scanning gate microscopy to image scar structures in an open quantum dot. Their results have revealed the existence of periodic scar offspring states that evolve and eventually contribute to a robust state, much in the way that the derivation of pointer states is predicted by quantum Darwinism."
