The exact dynamics of a Jaynes-Cummings model for a qubit interacting with a continuous distribution of bosons, characterized by a special form of the spectral density, is evaluated analytically. The ...
Quantum decoherence in strongly correlated electron system
Quantum decoherence strongly correlated electron system
2010/11/19
Physical phenomena in the vicinity of metal-to-insulator transition are analyzed by considering decoherence process between the localized state, |L>and the itinerant state, |I> in strongly correlated ...
How long it takes para-positronium AND ortho-positronium to become para-positronium OR ortho-positronium? Decoherence of positronium in a matter
para-positronium AND ortho-positronium para-positronium ortho-positronium
2010/11/11
Because of small gap between the energy of para-positronium (p-Ps) and ortho-positronium (o-Ps) it was assumed the possibility of the existence of superposition of p-Ps and o-Ps states as a result of...

This study deals with the further development of nuclear spin model of scalable quantum register, which presents the one-dimensional chain of the magnetic atoms with nuclear spins 1/2, substituting th...
Decoherence as a signature of an excited state quantum phase transition
Decoherence excited state quantum phase transition

We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presenc...
Decoherence of Electron Waves Due to Induced Charges Moving Through a Nearby Resistive Material
Electron Waves Charges a Nearby Resistive Material
2010/10/13
An experiment in which decoherence, i.e. the transition from quantum to classical behaviour, can be studied in detail was proposed by Anglin and Zurek [1] and has now been realized. An electron beam i...
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...
New strategy for suppressing decoherence in quantum computation
New strategy suppressing decoherence quantum computation
2010/10/13
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...
