  1. 1. Exploring the Elegant Bell Inequality

    University dissertation from Stockholm : Stockholm University

    Author : Irina Dumitru; Ingemar Bengtsson; Marcin Pawłowski; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bell inequality; Symmetric Informationally Complete POVM; Device Independent Certification; Theoretical Physics; teoretisk fysik;

    Abstract : In quantum information, device independent certification is a matter of both practical and fundamental interest. In this thesis, we explore the use of a particular Bell inequality, known as the elegant Bell inequality, in device independent certification. READ MORE

  2. 2. Bell tests and the no-signalling assumption

    University dissertation from Stockholm University

    Author : Massimiliano Smania; Mohamed Bourennane; Ingemar Bengtsson; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum; quantum optics; Bell tests; CHSH inequality; entanglement; Physics; fysik;

    Abstract : Bell's theorem was originally meant for testing fundamental properties of Nature, namely local realism. However, through the years it has become a powerful device for certifying encryption security, randomness, and entanglement among other properties. READ MORE

  3. 3. Experiments with Entangled Photons Bell Inequalities, Non-local Games and Bound Entanglement

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Muhammad Sadiq; Mohamed Bourennane; Rupert Ursin; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : Quantum mechanics is undoubtedly a weird field of science, which violates many deep conceptual tenets of classical physics, requiring reconsideration of the concepts on which classical physics is based. For instance, it permits persistent correlations between classically separated systems, that are termed as entanglement. READ MORE

  4. 4. A Classical-Light Attack on Energy-Time Entangled Quantum Key Distribution, and Countermeasures

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jonathan Jogenfors; Jan-Åke Larsson; Arnt Inge Vistnes; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Key Distribution; Energy-Time Entanglement; Quantum Information; Kvantkryptering; Energi-Tid-Snärjning; Kvantinformation;

    Abstract : Quantum key distribution (QKD) is an application of quantum mechanics that allowstwo parties to communicate with perfect secrecy. Traditional QKD uses polarization of individual photons, but the development of energy-time entanglement could lead to QKD protocols robust against environmental effects. READ MORE

  5. 5. Non-contextual inequalities and dimensionality

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johan Ahrens; Mohamed Bourennane; Otfried Gühne; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : This PhD-thesis is based on the five experiments I have performed during mytime as a PhD-student. Three experiments are implementations of non-contextualinequalities and two are implementations of witness functions for classical- andquantum dimensions of sets of states. READ MORE
