The problem of the classical limit of quantum mechanics and the role of self-induced decoherence
(Springer, 2006-12)
Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of a closed quantum system ...
Quantum Decoherence: A Logical Perspective
(Springer, 2014-11)
The so-called classical limit of quantum mechanics is generally studied in terms of the decoherence of the state operator that characterizes a system. This is not the only possible approach to decoherence. In previous works ...
Decoherence from qubit-qubit dipolar interaction in an all silicon quantum computer
(Sociedad Mexicana de Física A.C., 2009)
Self-induced decoherence and the classical limit of quantum mechanics
(University of Chicago Press, 2005-12)
In this paper we argue that the emergence of the classical world from the underlying quantum reality involves two elements: self‐induced decoherence and macroscopicity. Self‐induced decoherence does not require the openness ...
Redundancy of classical and quantum correlations during decoherence
(American Physical Society, 2009-10)
We analyze the time dependence of entanglement and total correlations between a system and fractions of its environment in the course of decoherence. For the quantum Brownian motion model, we show that the entanglement and ...
Quantum engineering: Protecting the quantum world
(Nature Publishing Group, 2001-08)
When quantum systems interact with the environment, classical properties emerge -- a process known as decoherence. Although decoherence is unavoidable, it may still be possible to manipulate the outcome.
Quantum irreversible decoherence behaviour in open quantum systems with few degrees of freedom: Application to 1H NMR reversion experiments in nematic liquid crystals
(American Institute of Physics, 2013-10)
An experimental study of NMR spin decoherence in nematic liquid crystals is presented. Decoherence dynamics can be put in evidence by means of refocusing experiments of the dipolar interactions. The experimental technique ...
Decoherence in current induced forces: Application to adiabatic quantum motors
(American Physical Society, 2015-08)
Current induced forces are not only related with the discrete nature of electrons but also with its quantum character. It is natural then to wonder about the effect of decoherence. Here, we develop the theory of current ...
