Roads to objectivity: Quantum Darwinism, Spectrum Broadcast Structures, and Strong quantum Darwinism – a review [PDF]
Quantum, 2021 The problem of objectivity, i.e. how to explain on quantum grounds the objective character of the macroscopic world, is one of the aspects of the celebrated quantum-to-classical transition. Initiated by W. H.

Emergence of Objectivity for Quantum Many-Body Systems [PDF]
Entropy, 2022 We examine the emergence of objectivity for quantum many-body systems in a setting without an environment to decohere the system’s state, but where observers can only access small fragments of the whole system.

Quantifying Decoherence via Increases in Classicality [PDF]
Entropy, 2021 As a direct consequence of the interplay between the superposition principle of quantum mechanics and the dynamics of open systems, decoherence is a recurring theme in both foundational and experimental exploration of the quantum realm.

Amplification, Inference, and the Manifestation of Objective Classical Information [PDF]
Entropy, 2022 Our everyday reality is characterized by objective information—information that is selected and amplified by the environment that interacts with quantum systems.

Correlations, Information Backflow, and Objectivity in a Class of Pure Dephasing Models [PDF]
Entropy, 2022 We critically examine the role that correlations established between a system and fragments of its environment play in characterising the ensuing dynamics.

Decoherence without entanglement and quantum Darwinism
Physical Review Research, 2020 It is often assumed 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 the system, thus washing away its quantum properties ...

Classifying Two-Body Hamiltonians for Quantum Darwinism
Physical Review XQuantum Darwinism is a paradigm to understand how classically objective reality emerges from within a fundamentally quantum universe. Despite the growing attention that this field of research has been enjoying, it is currently not known what specific ...

Non-Markovianity hinders Quantum Darwinism. [PDF]
Sci Rep, 2016 AbstractWe investigate Quantum Darwinism and the emergence of a classical world from the quantum one in connection with the spectral properties of the environment. We use a microscopic model of quantum environment in which, by changing a simple system parameter, we can modify the information back flow from environment into the system and therefore its ...

Quantum Darwinism and the spreading of classical information in non-classical theories [PDF]
Quantum, 2022 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.
