Is Quantum Darwinism Really Only About Quantum Mechanics’ Interaction with Its Environment?

Quantum Darwinism Could Explain What Makes Reality Real

Selected notes ~

+  So far, so good for quantum Darwinism. “All these studies see what is expected, at least approximately,” Zurek said. Riedel says we could hardly expect otherwise, though: In his view, QD is really just the careful and systematic application of standard quantum mechanics to the interaction of a quantum system with its environment. Although this is virtually impossible to do in practice for most quantum measurements, if you can sufficiently simplify a measurement, the predictions are clear, he said: “QD is most like an internal self-consistency check on quantum theory itself.”

Contrary to popular belief, says physicist Adán Cabello, “quantum theory perfectly describes the emergence of the classical world.”

+  Wojciech Zurek, a theoretical physicist at Los Alamos National Laboratory in New Mexico, developed the quantum Darwinism theory in the 2000s to account for the emergence of objective, classical reality.

+  An atom typically can’t be assigned a definite position, for example—we can merely calculate the probability of finding it in various places. The vexing question then becomes: How do quantum probabilities coalesce into the sharp focus of the classical world?
