Decoherence, Entanglement and Information
Protection in Complex Quantum Systems
NATO Science Series
A Series presenting the results of scientific meetings supported under the NATO Science
Programme.
The Series is published by IOS Press, Amsterdam, and Springer (formerly Kluwer Academic
Publishers) in conjunction with the NATO Public Diplomacy Division.
Sub-Series
I. Life and Behavioural Sciences IOS Press
II. Mathematics,Physics and Chemistry Springer (formerly Kluwer Academic Publishers)
III.Computer and Systems Science IOS Press
IV.Earth and Environmental Sciences Springer (formerly Kluwer Academic Publishers)
The NATO Science Series continues the series of books published formerly as the NATO ASI Series.
The NATO Science Programme offers support for collaboration in civil science between scientists of
countries of the Euro-Atlantic Partnership Council.The types of scientific meeting generally supported
are “Advanced Study Institutes”and “Advanced Research Workshops”, and the NATO Science Series
collects together the results of these meetings.The meetings are co-organized by scientists from
,
NATO countries and scientists from NATOs Partner countries – countries of the CIS and Central and
Eastern Europe.
Advanced Study Institutesare high-level tutorial courses offering in-depth study of latest advances
in a field.
Advanced Research Workshops are expert meetings aimed at critical assessment of a field, and
identification of directions for future action.
As a consequence of the restructuring of the NATO Science Programme in 1999, the NATO Science
Series was re-organized to the four sub-series noted above. Please consult the following web sites for
information on previous volumes published in the Series.
