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 decoherence is caused by the interaction in which the environment in effect monitors certain observables of the system, destroying coherence between the pointer states corresponding to their eigenvalues. This leads to environment-induced superselection or einselection, a quantum process associated… 

Decoherence, irreversibility, and selection by decoherence of exclusive quantum states with definite probabilities

The problem investigated in this paper is einselection, i. e. the selection of mutually exclusive quantum states with definite probabilities through decoherence. Its study is based on a theory of

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.

Quantifying Decoherence via Increases in Classicality

This work introduces two quantifiers of classicality via the Jordan product and uncertainty, respectively, and then employs them to quantify decoherence from an information-theoretic perspective and studies the influence of the system on the environment.

Decoherence, entanglement decay, and equilibration produced by chaotic environments.

It is shown that in the semiclassical limit the equilibration state is arbitrarily close to a separable state, and the environment leads the central system to equilibrate to the time average of its reduced density matrix, which corresponds to a diagonal state in the preferential energy eigenbasis.

Quantum decoherence with holography

A bstractQuantum decoherence is the loss of a system’s purity due to its interaction with the surrounding environment. Via the AdS/CFT correspondence, we study how a system decoheres when its

The problem of identifying the system and the environment in the phenomenon of decoherence

The term “decoherence” generally refers to the quantum process that supposedly turns a pure state into a mixed state, which is diagonal in a well-defined basis. The orthodox explanation of the

Self-Induced Selection: A New Approach to Quantum Decoherence

According to Zurek, decoherence is a process resulting from the interaction between a quantum system and its environment; this process singles out a preferred set of states, usually called pointer

Localization effects induced by decoherence in superpositions of many-spin quantum states

The spurious interaction of quantum systems with their environment known as decoherence leads, as a function of time, to a decay of coherence of superposition states. Since the interactions between

5 Introduction to Decoherence Theory

This introduction to the theory of decoherence is aimed at readers with an interest in the science of quantum information. In that field, one is usually content with simple, abstract descriptions of

Einselection from incompatible decoherence channels

Decoherence of quantum systems from entanglement with an unmonitored environment is, to date, the most compelling explanation of the emergence of a classical picture from a quantum world. While it is



Decoherence, chaos, quantum-classical correspondence, and the algorithmic arrow of time

The environment – external or internal degrees of freedom coupled to the system – can, in effect, monitor some of its observables. As a result, the eigenstates of these observables decohere and

Environment-induced superselection rules

We show how the correlations of a quantum system with other quantum systems may cause one of its observables to behave in a classical manner. In particular, "reduction of the wave packet," postulated

It is shown, in a simple homogeneous isotropic model, that the density matrix of the Universe will decohere if the long-wavelength modes of an inhomogeneous massless scalar field are traced out and the coherence width decreases as the scale factor increases, which has implications for the arrow of time.

Decoherence and the Appearance of a Classical World in Quantum Theory

In the last decade decoherence has become a very popular topic mainly due to the progress in experimental techniques which allow monitoring of the process of decoherence for single microscopic or

It is shown how recurrence in the quantum cat map is lost and classical ergodicity is recovered due to the effect of the environment, and how environment-induced effects can destroy this localization of the kicked rotor.

Decoherence and quantum fluctuations

We show that the zero-point fluctuations of the intrinsic electromagnetic environment limit the phasecoherence time in all mesoscopic systems at low temperatures. We derive this quantum-noise-limited

Decoherence of quantum superpositions through coupling to engineered reservoirs

Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.

Decoherence and the Existential Interpretation of Quantum Theory, or ”No Information Without Representation”

Quantum theory allows many more states for the objects described by it than we seem to encounter. Moreover, quantum dynamics (especially the dynamics required to model measurements) takes simple,

The emergence of classical properties through interaction with the environment

The dependence of macroscopic systems upon their environment is studied under the assumption that quantum theory is universally valid. In particular scattering of photons and molecules turns out to
