Abstract: We live in a universe that is fundamentally quantum. Yet, our everyday world appears to be resolutely classical. The underlying quantumness of our universe has been by now convincingly established by careful laboratory experiments. They attest to the quantum nature of systems of various sizes and, above all, of the “stuff” (e.g., atoms) everything is made of. The evidence for the absence of quantumness in our world comes from ongoing everyday “experiments” — our perceptions — that are poorly controlled, but, because of their immediate, personal nature, are immensely persuasive.
Why does quantum theory result in a familiar “classical reality” in quantum systems? How and why does quantum theory result in our classical perceptions?
