Decoherence in quantum open systems revisited
Robert Alicki
TL;DR
This paper challenges common beliefs in environmental decoherence theory, showing that linear harmonic oscillator baths are not universally applicable and that chaos does not necessarily enhance decoherence efficiency.
Contribution
It revisits and corrects widely held assumptions about the universality of linear baths and the role of chaos in decoherence processes.
Findings
Linear harmonic oscillator baths are not a universal decoherence model.
Chaotic environments are not necessarily more effective decoherers.
The folklore assumptions in decoherence theory are shown to be incorrect.
Abstract
The following statements belonging to the folklore of the theory of environmental decoherence are shown to be incorrect: 1) linear coupling to harmonic oscillator bath is a universal model of decoherence, 2) chaotic environments are more efficient decoherers.
