The Problem of Quantum Measurement Quantum Measurement as Thermodynamic Limit
We derive the probabilities of measurement results from Schroedinger’s equation plus a definition of macroscopic as a particular kind of thermodynamic limit. Bohr’s insight that a measurement apparatus must be classical in nature and classically describable is made precise in a mathematical sense analogous to the procedures of classical statistical mechanics and the study of Hamiltonian heat ba...
متن کاملQuantum Measurement Problem, Decoherence, and Quantum Systems Selfdescription
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 ...
متن کاملLogic Programming as Quantum Measurement
The emphasis is made on the juxtaposition of (quantum theorem) proving versus quantum (theorem proving). The logical contents of verification of the statements concerning quantum systems is outlined. The Zittereingang (trembling input) principle is introduced to enhance the resolution of predicate satisfiability problem provided the processor is in a position to perform operations with continuo...
متن کاملNested Quantum Walks with Quantum Data Structures
We develop a new framework that extends the quantum walk framework of Magniez, Nayak, Roland, and Santha, by utilizing the idea of quantum data structures to construct an efficient method of nesting quantum walks. Surprisingly, only classical data structures were considered before for searching via quantum walks. The recently proposed learning graph framework of Belovs has yielded improved uppe...
متن کاملQuantum Measurement and Quantum Gravity
At present, there are two possible, and equally plausible, explanations for the physics of quantum measurement. The first explanation, known as the many-worlds interpretation, does not require any modification of quantum mechanics, and asserts that at the time of measurement the Universe splits into many branches, one branch for every possible alternative. The various branches do not interfere ...
