We 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 non-Markovian character. We show that the presence of memory effects hinders the emergence of classical objective reality, linking these two apparently… 

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 noninteracting

On the relation between quantum Darwinism and approximate quantum Markovianity

There are strong evidences in the literature that quantum non-Markovianity would hinder the presence of Quantum Darwinism. In this note, we study the relation between quantum Darwinism and

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

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.

Quantum Darwinism and non-Markovianity in a model of quantum harmonic oscillators

To explain aspects of the quantum-to-classical transition, quantum Darwinism explores the fact that, due to interactions between a quantum open system and its surrounding environment, information

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

Classicality with(out) decoherence: Concepts, relation to Markovianity, and a random matrix theory approach

Answers to the question how a classical world emerges from underlying quantum physics are revisited, connected and extended as follows. First, three distinct concepts are compared: decoherence in

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.

Many-Body Localization and the Emergence of Quantum Darwinism

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.

Experimental signature of quantum Darwinism in photonic cluster states

We report on an experimental assessment of the emergence of Quantum Darwinism (QD) from engineered open-system dynamics. We use a photonic hyperentangled source of graph states to address the effects

Objectivity in the non-Markovian spin-boson model

Objectivity constitutes one of the main features of the macroscopic classical world. An important aspect of the quantum-to-classical transition issue is to explain how such a property arises from the



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.

Entanglement and non-markovianity of quantum evolutions.

Two different measures of non-markovianity are introduced that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts when complete tomographic knowledge about the evolution is available and when no information whatsoever is available.

Degree of non-Markovianity of quantum evolution.

We propose a new characterization of non-Markovian quantum evolution based on the concept of non-Markovianity degree. It provides an analog of a Schmidt number in the entanglement theory and reveals

Non-Markovianity and reservoir memory of quantum channels: a quantum information theory perspective

It is shown that for non-Markovian quantum channels this is not always true: surprisingly the capacity of a longer channel can be greater than of a shorter one and harnessing non- Markovianity may improve the efficiency of quantum information processing and communication.

Quantum Darwinism in an everyday environment: huge redundancy in scattered photons.

It is demonstrated that this realistic model exhibits fast and extensive proliferation of information about the object into the environment and results in redundancies orders of magnitude larger than the exactly soluble models considered to date.

Decoherence, einselection, and the quantum origins of the classical

as quantum engineering. In the past two decades it has become increasingly clear that many (perhaps all) of the symptoms of classicality can be induced in quantum systems by their environments. Thus

Measure for the degree of non-markovian behavior of quantum processes in open systems.

We construct a general measure for the degree of non-Markovian behavior in open quantum systems. This measure is based on the trace distance which quantifies the distinguishability of quantum states.

Redundancy of classical and quantum correlations during decoherence

We analyze the time dependence of entanglement and total correlations between a system and fractions of its environment in the course of decoherence. For the quantum Brownian motion model, we show

Environment-induced decoherence and superselection have been a subject of intensive research over the past two decades, yet their implications for the foundational problems of quantum mechanics, most
