@inproceedings{Zurek2009QuantumD, title={Quantum Darwinism}, author={Wojciech Zurek}, year={2009} }

Quantum Darwinism describes the proliferation, in the environment, of multiple records of selected states of a quantum system. It explains how the fragility of a state of a single quantum system can lead to the classical robustness of states of their correlated multitude; shows how effective ‘wavepacket collapse’ arises as a result of proliferation throughout the environment of imprints of the states of quantum system; and provides a framework for the derivation of Born’s rule, which relates…

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…

Anti-Zeno-based dynamical control of the unfolding of quantum Darwinism

- Computer SciencePhysical Review Research
- 2020

By adjusting the features of the system-environment interaction through a simple suitable control, the rate at which a multiparty environment acquires information on the state of a quantum system can be tuned, thus effectively slowing down or speeding up the temporal unfolding of redundant encoding of information responsible for the emergence of classicality.

Generic emergence of classical features in quantum Darwinism.

- PhysicsNature communications
- 2015

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.

Non-Markovianity hinders Quantum Darwinism

- PhysicsScientific reports
- 2016

It is shown that the presence of memory effects hinders the emergence of classical objective reality, linking these two apparently unrelated concepts via a unique dynamical feature related to decoherence factors.

Quantum theory of the classical: quantum jumps, Born’s Rule and objective classical reality via quantum Darwinism

- PhysicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2018

Three insights into the transition from quantum to classical that are based on the recognition of the role of the environment are described, including the derivation of preferred sets of states that help to define what exists—the authors' everyday classical reality.

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 system…

A whole box of Pandoras: systems, boundaries and free will in quantum theory1

It is shown that the paradoxes of quantum theory can be traced to an assumption that observers can know which physical degrees of freedom are causally responsible for each of their experiences, and a quantum theory without this assumption is proposed.

Quantum Darwinism and Computability Theory

This paper examines whether unitary evolution alone is sufficient to explain emergence of the classical world from the perspective of computability theory. Specifically, it looks at the problem of…

Random unitary evolution model of quantum Darwinism with pure decoherence

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.…

Quantum Darwinism in quantum Brownian motion.

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.

Measurements transfer information about a system to the apparatus, and then further on – to observers and (often inadvertently) to the environment. I show that even imperfect copying essential in…

Quantum Darwinism: Entanglement, branches, and the emergent classicality of redundantly stored quantum information

The results show that the presence of redundancy divides information about the system into three parts: classical ( redundant); purely quantum; and the borderline, undifferentiated or "nonredundant," information.

A Simple Example of “Quantum Darwinism”: Redundant Information Storage in Many-Spin Environments

- Computer Science, Physics
- 2005

This paper examines how many-qubit (or many-spin) environments can store information about a single system and shows that randomly chosen states of the environment almost always encode the information so that an observer must capture a majority of the Environment to deduce the system’s state.

It is shown that only preferred pointer states of the system can leave a redundant and therefore easily detectable imprint on the environment.
