Quantum Measurement Problem, Decoherence, and Quantum Systems Selfdescription
Sergey Nikolaevich Mayburov · arXiv (Cornell University) · 2002
Quantum Measurements regarded in Systems Selfdescription framework for measuring system (MS) consist of measured state S environment E and observer $O$ processing input S signal. $O$ regarded as quantum object which interaction with S,E obeys to Schrodinger equation (SE) and from it and Breuer selfdescription formalism S information for $O$ reconstructed. In particular S state collapse obtained if $O$ selfdescription state has the dual structure $L_T=\cal H \bigotimes L_V$ where $\cal H$ is Hilbert space of MS states $Ψ_{MS}$. $\cal L_V$ is the set with elements $V^O=|O_j> $ defined by $O$ state decoherence via $O$ - E interactions.
