### Many-Body Localization and the Emergence of Quantum Darwinism

- Computer ScienceEntropy
- 2021

It is shown that a highly disordered evolution may reduce the spoiling of redundancy in the presence of intra-environment interactions and suggest the key role that disorder may play when the environment is of a thermodynamic size.

### Quantum Darwinism in a Composite System: Objectivity versus Classicality

- PhysicsEntropy
- 2021

It is established that a non-zero quantum discord is shared between the composite system and the environment, thus violating the conditions of strong Darwinism, and implies a dichotomy between objectivity and classicality that emerges when considering composite systems.

### Commutativity and the emergence of classical objectivity

- Computer ScienceJournal of Physics Communications
- 2022

This work examines how the ability of a system to redundantly proliferate relevant information about its pointer states is affected when it is coupled to multiple baths and sheds light on the role that commutativity between the various system-bath interaction terms plays when establishing the conditions for classical objectivity to be supported.

### Suppressing information storage in a structured thermal bath

- Physics
- 2021

Quantum systems interacting with environments tend to have their information lost from transmission through the correlations generated with the degrees of freedom of the environment. For situations…

### Eavesdropping on the Decohering Environment: Quantum Darwinism, Amplification, and the Origin of Objective Classical Reality.

- PhysicsPhysical review letters
- 2022

"How much information about a system S can one extract from a fragment F of the environment E that decohered it?" is the central question of Quantum Darwinism. To date, most answers relied on the…

### Correlations, Information Backflow, and Objectivity in a Class of Pure Dephasing Models

- PhysicsEntropy
- 2022

We critically examine the role that correlations established between a system and fragments of its environment play in characterising the ensuing dynamics. We employ a dephasing model with different…

### Nonlocality breaks the relations between measures of quantum objectivity

- Physics
- 2022

We show the existence of two diﬀerent aspects of quantum objectivity, “redundancy” and “consensus”. Though used as synonyms in this context, we prove that they quantify diﬀerent features of the…

### Amplification, Inference, and the Manifestation of Objective Classical Information

- Computer ScienceEntropy
- 2022

The accessible information is related to the error probability for optimal detection and has the same behavior as the quantum Chernoff bound, which reflects amplification and provides a universal approach, as well as a single-shot framework, to quantify records of the missing, classical information about S.

### Decoherence and objectivity in higher spin environments

- PhysicsPhysical Review A
- 2021

We analyze decoherence and objectivization processes in spin-spin models for arbitrary spins. We first derive the most general analytic form of the decoherence factor in the measurement limit, where…

### Witnessing objectivity on a quantum computer

- PhysicsQuantum Science and Technology
- 2021

Understanding the emergence of objectivity from the quantum realm has been a long standing issue strongly related to the quantum to classical crossover. Quantum Darwinism provides an answer,…

### Application of quantum Darwinism to a structured environment

- Computer Science
- 2017

By quantifying redundancy, this work concretely shows it to act as a witness to non-Markovianity in the same way as the trace distance does for nondivisible dynamical maps.

### Quantum Darwinism in a Composite System: Objectivity versus Classicality

It is established that a non-zero quantum discord is shared between the composite system and the environment, thus violating the conditions of strong Darwinism, and implies a dichotomy between objectivity and classicality that emerges when considering composite systems.

### Quantum darwinism in a mixed environment.

- Computer SciencePhysical review letters
- 2009

Even such hazy environments eventually reveal the state of the system, although now the intercepted environment fragment must be larger by approximately (1-h)(-1) to gain the same information about the system.

### Role of information backflow in the emergence of quantum Darwinism

- PhysicsPhysical Review A
- 2019

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 noninteracting…

### Revealing the Emergence of Classicality Using Nitrogen-Vacancy Centers.

- PhysicsPhysical review letters
- 2019

This experiment demonstrates that, in the course of the decoherence of S, redundant information is indeed imprinted onto E, giving rise to incipient classical objectivity, the first laboratory verification of the process responsible for the emergence of the objective classical world from the underlying quantum substrate.

### Random unitary evolution model of quantum Darwinism with pure decoherence

- Physics
- 2015

We study the behavior of Quantum Darwinism [W.H. Zurek, Nat. Phys. 5, 181 (2009)] within the iterative, random unitary operations qubit-model of pure decoherence [J. Novotný, G. Alber, I. Jex, New J.…

### Decoherence without entanglement and quantum Darwinism

- PhysicsPhysical Review Research
- 2020

It is commonly believed that decoherence arises as a result of the entangling interaction between a quantum system and its environment, as a consequence of which the environment effectively measures…

### Generic Emergence of Objectivity of Observables in Infinite Dimensions.

- PhysicsPhysical review letters
- 2018

This work proves two theorems that bound the emergence of objectivity, first for finite mean energy systems, and then for systems that can only be prepared in states with an exponential energy cutoff, and shows that the latter class includes any bounded-energy subset of single-mode Gaussian states.

### Objectivity (or lack thereof): Comparison between predictions of quantum Darwinism and spectrum broadcast structure

- Computer SciencePhysical Review A
- 2018

It is found that quantum Darwinism can apparently emerge under the Perez trace even when spectrum broadcast structure does not emerge, and the majority of the quantum mutual information between system and environment fractions is in fact quantum in nature.

### Strong Quantum Darwinism and Strong Independence are Equivalent to Spectrum Broadcast Structure.

- PhysicsPhysical review letters
- 2019

It is shown that strong quantum Darwinism is sufficient and necessary to signal state objectivity without the requirement of strong independence, thereby making fundamental progress toward understanding and solving the emergence of classicality from the quantum world.
