Pointer States and Quantum Darwinism with Two-Body Interactions [PDF]
Entropy, 2023 Quantum Darwinism explains the emergence of classical objectivity within a quantum universe. However, to date, most research on quantum Darwinism has focused on specific models and their stationary properties.

Quantum Darwinism in a Composite System: Objectivity versus Classicality [PDF]
Entropy, 2021 We investigate the implications of quantum Darwinism in a composite quantum system with interacting constituents exhibiting a decoherence-free subspace. We consider a two-qubit system coupled to an N-qubit environment via a dephasing interaction.

Composite Discordant States and Quantum Darwinism [PDF]
Entropy, 2022 The framework of Quantum Darwinism strives at characterizing the quantum-to-classical transition by introducing the concept of redundancy of information—as measured by Mutual Information—that a set of observers would acquire on the state of a physical ...

Quantum Theory of the Classical: Einselection, Envariance, Quantum Darwinism and Extantons [PDF]
Entropy, 2022 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 ...

Many-Body Localization and the Emergence of Quantum Darwinism [PDF]
Entropy, 2021 Quantum Darwinism (QD) is the process responsible for the proliferation of redundant information in the environment of a quantum system that is being decohered.

Relationship between Information Scrambling and Quantum Darwinism [PDF]
Entropy, 2023 A quantum system interacting with a multipartite environment can induce redundant encoding of the information of a system into the environment, which is the essence of quantum Darwinism.

Non-Perfect Propagation of Information to a Noisy Environment with Self-Evolution [PDF]
Entropy, 2022 We study the non-perfect propagation of information for evolving a low-dimensional environment that includes self-evolution as well as noisy initial states and analyse the interrelations between the degree of objectivization and environment parameters ...

Limits to Perception by Quantum Monitoring with Finite Efficiency [PDF]
Entropy, 2021 We formulate limits to perception under continuous quantum measurements by comparing the quantum states assigned by agents that have partial access to measurement outcomes.

Emergence of Noncontextuality under Quantum Darwinism
PRX Quantum, 2021 Quantum Darwinism proposes that the proliferation of redundant information plays a major role in the emergence of objectivity out of the quantum world. Is this kind of objectivity necessarily classical?

Thermality versus Objectivity: Can They Peacefully Coexist? [PDF]
Entropy, 2021 Under the influence of external environments, quantum systems can undergo various different processes, including decoherence and equilibration. We observe that macroscopic objects are both objective and thermal, thus leading to the expectation that both ...
