Quantum Darwinism, Classical Reality, and the Randomness of Quantum Jumps

Abstract

Tracing flows of information in our quantum Universe explains why we see the world as classical.

This manuscript, after cuts and edits to comply with Physics Today limits and style, was published last October. It may have some rough edges, but it also contains technical elaborations omitted from the published version for lack of space that may be of interest to some readers. Thus, while the essence is the same, but there are differences (starting with the title and abstract)
