Decoherence, Anti-Decoherence, and Fisher Information [PDF]
Entropy, 2021 In this work, we study quantum decoherence as reflected by the dynamics of a system that accounts for the interaction between matter and a given field. The process is described by an important information geometry tool: Fisher’s information measure (FIM).

Environmental decoherence versus intrinsic decoherence [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2012 We review the difference between standard environmental decoherence and ‘intrinsic decoherence’, which is taken to be an ineluctable process of Nature. Environmental decoherence is typically modelled by spin bath or oscillator modes—we review some of the unanswered questions not captured by these models, and also the application of them to experiments.

Dynamics of decoherence: Universal scaling of the decoherence factor [PDF]
Physical Review A, 2016 We study the time dependence of the decoherence factor (DF) of a qubit globally coupled to an environmental spin system (ESS) which is driven across the quantum critical point (QCP) by varying a parameter of its Hamiltonian in time $t$ as $1 -t/τ$ or $-t/τ$, to which the qubit is coupled starting at the time $t \to -\infty$; here, $τ$ denotes the ...

Decoherence in the chemical compass: the role of decoherence for avian magnetoreception [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2012 Contrary to the usual picture that decoherence destroys quantum properties and causes the quantum-to-classical transition, we argue that decoherence can also play a constructive role in driving quantum dynamics and amplifying its results to macroscopic scales.

Entropy, 2022 Quantum decoherence is crucial to understanding the emergence of the classical world from the underlying quantum reality. Decoherence dynamics are unitary, although they superselect a preferred eigenbasis.

The Metaphysics of Decoherence [PDF]
Erkenntnis, 2021 AbstractThe paper investigates the type of realism that best suits the framework of decoherence taken at face value without postulating a plurality of worlds, or additional hidden variables, or non-unitary dynamical mechanisms. It is argued that this reading of decoherence leads to a type of perspectival realism which is extremely radical, especially ...

Decoherence and Thermalization [PDF]
Physical Review Letters, 2007 We present a rigorous analysis of the phenomenon of decoherence for general N-level systems coupled to reservoirs of free massless bosonic fields. We apply our general results to the specific case of the qubit. Our approach does not involve master equation approximations and applies to a wide variety of systems which are not explicitly solvable.

On the effect of decoherence on quantum tunnelling
SN Applied Sciences, 2021 This work proposes a series of quantum experiments that can, at least in principle, allow for examining microscopic mechanisms associated with decoherence.

Decoherence-Induced Sudden Death of Entanglement and Bell Nonlocality
Photonics, 2022 Decoherence due to the unwanted interaction between a quantum system and environment leads to the degradation of quantum coherence. In particular, for an entangled state, decoherence makes a loss of entanglement and Bell nonlocality known as entanglement
