Darwinism and Extantons
- Authors: Wojciech Hubert Zurek
- Abstract summary: Core quantum postulates including the superposition principle and the unitarity of evolutions are natural and strikingly simple.
I show that -- when supplemented with a limited version of predictability (captured in the textbook accounts by the repeatability postulate) -- these core postulates can account for all the symptoms of classicality.

- Abstract: Core quantum postulates including the superposition principle and the
unitarity of evolutions are natural and strikingly simple. I show that -- when
supplemented with a limited version of predictability (captured in the textbook
accounts by the repeatability postulate) -- these core postulates can account
for all the symptoms of classicality. In particular, both objective classical
reality and elusive information about reality arise, via quantum Darwinism,
from the quantum substrate.

We look into the ontology of quantum theory as distinct from that of the classical theory in the sciences.
Within this framework, theories are conceptual constructs applying to models generated in the phenomenal world within limited contexts.

Two particles are identical if all their intrinsic properties, such as spin and charge, are the same.
Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles.
We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

non-classical theories [0.0]
Quantum Darwinism posits that the emergence of a classical reality relies on the spreading of classical information from a quantum system to many parts of its environment.
We find that every theory with non-classical features that admits this idealized spreading of classical information must have both entangled states and entangled measurements.
Our result suggests the counter-intuitive general principle that in the presence of local non-classicality, a classical world can only emerge if this non-classicality can be "amplified" to a form of entanglement.

As an application, we show that imaginarity plays a crucial role for state discrimination.

Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon.
We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space.
The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.
