  1. 1. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization

    Författare :Fritiof Wallentin; Andrei Khrennikov; Kisil Vladimir; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; contextuality; probabilistic interpretation; Born’s rule; frequentist interpretation; unitary representations; classical statistical mechanics; Koopman-von Neumann formulation; hidden-variable model; quantization.; Matematik; Mathematics;

    Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

  3. 2. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information

    Författare :Elias Amselem; Mohamed Bourennane; Antonio Acín; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; fysik; Physics;

    Sammanfattning : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. LÄS MER

  4. 3. Eat, Meet, Fly, Repeat : the contextuality of business travellers’ meals

    Författare :Joachim Sundqvist; Carita Bengs; Agneta Hörnell; Ute Walter; Christian Fuentes; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meal science; meal practice; business travel; social practice theory;

    Sammanfattning : Meals are an important part of everyday life, both for the persons who engage in them and for the industry that makes them. For business travellers, meals are engaged in differently when they are travelling compared when they are home. Tens of millions of meals are engaged in each year by persons who are conducting business trips. LÄS MER

  5. 4. Photonic quantum information and experimental tests of foundations of quantum mechanics

    Författare :Magnus Rådmark; Mohamed Bourennane; John Rarity; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; Physics; Fysik; fysik; Physics;

    Sammanfattning : Entanglement is a key resource in many quantum information schemes and in the last years the research on multi-qubit entanglement has drawn lots of attention. In this thesis the experimental generation and characterisation of multi-qubit entanglement is presented. Specifically we have prepared entangled states of up to six qubits. LÄS MER

  7. 5. Configurations in Quantum Information

    Författare :Kate Blanchfield; Ingemar Bengtsson; Erik Sjöqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : Measurements play a central role in quantum information. This thesis looksat two types: contextual measurements and symmetric measurements. Contextualityoriginates from the Kochen-Specker theorem about hidden variablemodels and has recently undergone a subtle shift in its manifestation. LÄS MER
