Quantum Darwinism recognizes that we-the observers-acquire our information about the "systems of interest" indirectly from their imprints on the environment. Here, we show that information about a system can be acquired from a mixed-state, or hazy, environment, but the storage capacity of an environment fragment is suppressed by its initial entropy. In the case of good decoherence, the mutual information between the system and the fragment is given solely by the fragment's entropy increase. For… Expand

Redundant imprinting of information in nonideal environments: Objective reality via a noisy channel
Quantum Darwinism provides an information-theoretic framework for the emergence of the objective, classical world from the quantum substrate. The key to this emergence is the proliferation ofExpand
Amplification, Decoherence, and the Acquisition of Information by Spin Environments
TLDR
It is demonstrated that the amplification of information in realistic spin environments can be quantified by the quantum Chernoff information, which characterizes the distinguishability of partial records in individual environment subsystems. Expand
Quantum Darwinism in a structured spin environment
We examine the emergence and suppression of signatures of quantum Darwinism when the system of interest interacts with a complex, structured environment. We introduce an extended spin-star modelExpand
The rise and fall of redundancy in decoherence and quantum Darwinism
A state selected at random from the Hilbert space of a many-body system is overwhelmingly likely to exhibit highly non-classical correlations. For these typical states, half of the environment mustExpand
Collisional unfolding of quantum Darwinism
We examine the emergence of objectivity via quantum Darwinism through the use of a collision model, i.e., where the dynamics is modeled through sequences of unitary interactions between the systemExpand
Generic emergence of classical features in quantum Darwinism.
TLDR
It is proved that the emergence of classical features along the lines of quantum Darwinism is a general feature of any quantum dynamics: observers who acquire information indirectly through the environment have effective access at most to classical information about one and the same measurement of the quantum system.

Redundant information from thermal illumination: quantum Darwinism in scattered photons
We study quantum Darwinism, the redundant recording of information about the preferred states of a decohering system by its environment, for an object illuminated by a blackbody. We calculate theExpand
Role of information backflow in the emergence of quantum Darwinism
Quantum Darwinism attempts to explain the emergence of objective reality of the state of a quantum system in terms of redundant information about the system acquired by independent noninteractingExpand
System information propagation for composite structures
We study in details decoherence process of a spin register, coupled to a spin environment. We use recently developed methods of information transfer study in open quantum systems to analyzeExpand

This work reports the first study of the dynamics of quantum Darwinism in a realistic model of decoherence, quantum Brownian motion, where the system leaves records whose redundancy increases rapidly with initial delocalization. Expand
Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
TLDR
Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete. Expand
Coupling-induced bipartite pointer states in arrays of electron billiards: quantum Darwinism in action?
TLDR
The ability of the robust states to create "offspring" indicates that quantum Darwinism is in action and the classical existence of bipartite pointer states is confirmed by comparing the quantum-mechanical and classical results. Expand
