In particular, the question whether the dynamical axiom of QM can be derived from other principles has been often considered. In this contribution, we show that unitary evolutions arise as a consequences of demanding preservation of entropy in the evolution of a single pure quantum system, and preservation of entanglement in the evolution of composite quantum systems. 6 Springer Science+Business Media, Inc., 2006 dynamical axiom of Quantum mechanics nationallicence entanglement preservation nationallicence entropy preservation nationallicence Hulpke Florian Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut Poulsen Uffe Department of Physics and Astronomy, University of Aarhus, DK-8000, Aarhus C., Denmark aut Sanpera Anna Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut Sen(De) Aditi Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut Sen Ujjwal Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut Lewenstein Maciej Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut Foundations of Physics Kluwer Academic Publishers-Plenum Publishers; http://www.springer-ny.com 36/4(2006-04-01), 477-499 0015-9018 36:4<477 2006 36 10701 https://doi.org/10.1007/s10701-005-9035-7 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s10701-005-9035-7 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Hulpke Florian Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut NATIONALLICENCE 700 1- Poulsen Uffe Department of Physics and Astronomy, University of Aarhus, DK-8000, Aarhus C., Denmark aut NATIONALLICENCE 700 1- Sanpera Anna Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut NATIONALLICENCE 700 1- Sen(De) Aditi Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut NATIONALLICENCE 700 1- Sen Ujjwal Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut NATIONALLICENCE 700 1- Lewenstein Maciej Institut für Theoretische Physik, Universität Hannover, D-30167, Hannover, Germany aut NATIONALLICENCE 773 0- Foundations of Physics Kluwer Academic Publishers-Plenum Publishers; http://www.springer-ny.com 36/4(2006-04-01), 477-499 0015-9018 36:4<477 2006 36 10701 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
