The main steps in the development of the ideas on decoherence are briefly reviewed, together with their present achievements. Unsolved problems are also pointed out.
We provide a theoretical explanation for two recent experiments on decoherence of Aharonov-Bohm oscillations in two- and multi-terminal ballistic rings. We consider decoherence due to charge fluctuati...
We have developed quantitative description of quantum coherent oscillations in the system of two coupled qubits in the presence of weak decoherence that in general can be correlated between the two qu...
The present note is devoted to a critique of some aspects of current decoherence theory.
Its main point is that several common claims related to decoherence theory are based on
questionable hidden a...

Controlable strong interaction of the qubit’s bath with an external system(i.e. with the bath’s environment) allows for choosing the conditions under which the decoherence of the qubit’s states can be...
We consider a wave packet of a charged particle passing through a cavity filled with photons at temperature T and investigate its localization and interference properties. It is shown that the wave pa...

Comment "Hidden assumptions in decoherence theory"

It is shown that the conclusion of the paper “Hidden assumptions in decoherence theory” [1] is the result of a misunderstanding of the concept of pointer states. It is argued that pointer states are s...

Quantum Decoherence Adiabatic Entanglement

In order to understand quantum decoherence of a quantum system due to its interaction with
a large system behaving classically, we introduce the concept of adiabatic quantum entanglement
based on th...
