  1. 1. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Karl Herlin; [2023]
    Nyckelord :quantum mechanics; quantum physics; philosophy of physics; interpretation of quantum mechanics; measurement problem; problem of preferred basis; problem of non-observability of interference; problem of definite outcomes; environment induced superselection rules; copenhagen interpretation; decoherence; irreducibility of classical concepts;

    Sammanfattning : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. LÄS MER

  3. 2. The black hole information paradox and holography

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Ona Mola Bertran; [2023]
    Nyckelord :information paradox; semiclassical physics; holography; AdS CFT correspondence; island formula; entanglement entropy;

    Sammanfattning : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. LÄS MER

  4. 3. On quantum systems and the measurement problem

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Nicolas Boulle; [2023]
    Nyckelord :Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

    Sammanfattning : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. LÄS MER

  5. 4. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Johanna Adbo; [2023]
    Nyckelord :QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

    Sammanfattning : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. LÄS MER

  7. 5. Experimental Test of Local Observer-Independence Using IBM’s Quantum Computer

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Ludvig Eidmann; Max Alteg; [2020]
    Nyckelord :;

    Sammanfattning : The precise interpretation of quantum mechanics is still open to discussion. A number of non-intercompatible interpretations, with a not unsignificant respective following, are at the time of writing still viable. LÄS MER
