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

- Physics

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…

### 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.

### Quantifying Decoherence via Increases in Classicality

- Computer ScienceEntropy
- 2021

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.

- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2011

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…

- Physics

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

- Physics
- 2002

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

- Physics
- 2011

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…

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

- Physics

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…

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.
